Unrecognized named-value: 'env'. for job conditional

[merlinstardust]

Describe the bug

Use of env in job conditionals causes an invalid config. Cross posting this from nektos/act#720

Expected behaviour

GitHub Actions should not error regarding ${{ !env.ACT }}

Actual behaviour

GitHub Actions says workflow is not valid because of ${{ !env.ACT }}

The workflow is not valid. .github/workflows/deploy.yml (Line: 11, Col: 13): Unrecognized named-value: 'env'. Located at position 2 within expression: !env.ACT

Base on https://docs.github.com/en/actions/reference/context-and-expression-syntax-for-github-actions#context-availability
env context is not available to job.if

You can create feature request at https://github.community/c/code-to-cloud/github-actions/41

[jacobq]

Did anyone create that feature request? I appreciate the link to contexts docs because this behavior was not at all obvious to me from this documentation:

The env context syntax allows you to use the value of an environment variable in your workflow file. You can use the env context in the value of any key in a step except for the id and uses keys. For more information on the step syntax, see "Workflow syntax for GitHub Actions."

So I guess they are using the term step to have some technically precise meaning, like a subkey of jobs.<job_id>.steps? Seems like the validator could give much better hints about the cause of the error here (e.g. "You attempted to used env, but env is not available in the context of ..... See this docs page for more details..."

[grintor]

I think it's suppose to work but doesn't. There is an an official example of using env in an if here:
https://docs.github.com/en/actions/learn-github-actions/environment-variables#using-contexts-to-access-environment-variable-values

[jacobq]

I think it's suppose to work but doesn't. There is an an official example of using env in an if here:

No, in that case the if is part of a step, which works (see jobs.<job_id>.steps.if in table linked below). The problem is that it is counter-intuitive for a developer who may be in the habit of thinking about the YAML file as something like a "shell script" wherein environment variables are globally accessible. The things that can be accessed (context) in a given place (workflow key) are listed here: https://docs.github.com/en/actions/learn-github-actions/contexts#context-availability
I think it would be very helpful if attempted accesses to unavailable contexts caused a warning to be generated (and perhaps linked to that table).

[grintor]

I see. Your explanation cleared that up for me. Thanks!

You're right, the official error message is no help.

[framerate]

Following up to this: I still think the docs are wrong. They state:

For example, an if conditional, which determines whether a job or step is sent to the runner,

This seems to imply that an env variable could be used in a job and a step but that doesn't seem to be the case.

[jacobq]

@framerate While it is annoying and, in my opinion, the docs are not very clear, I do not see any outright errors in these docs. They make it clear that you can always use environment variables at the lowest level (commands being executed on the "runner") and hint that "different points in the workflow" have access to different things. Perhaps one thing they could do to make it better would be to explain that when they say "GitHub Actions" they are apparently talking a specific component of the system, e.g. (emphasis added)

• "Environment variables are always interpolated on the virtual machine runner. However, parts of a workflow are processed by GitHub Actions and are not sent to the runner."

• "The docs try to explain this by saying: "You will commonly use either the env or github context to access environment variable values in parts of the workflow that are processed before jobs are sent to runners."

[framerate]

Right. That part is okay but the line:

 For example, an if conditional, which determines whether a job or step is sent to the runner, is always processed by GitHub Actions

I believe is completely wrong, isnt it? Or at least out of place since an env variables CANNOT be used in a job, even if an "if" can. So why say "job" here at all? It just makes people think we can use an env variables since that's the section we're reading.

Removing the words "job or" from that line would probably have removed my confusion at least.

[jacobq]

Maybe this is an English language "nit", but I think by using "which" instead of "that" it gives the wrong impression (i.e. explaining what an if statement might do rather than clarifying that we're talking about a specific if statement that does a particular thing: determining whether or not something gets sent to the runner, which means it is happening on "GitHub Actions" not on "the runner" and thus needs to read it from the env context.

[framerate]

Well I wasted a few dollars of minutes and a few hours of my day based on that sentence so whether or not everyone gets confused by it I can say with certainty I got confused and frustrated by it.

Whether or not anyone wants to fix it is beyond the scope of my authority but enough of these frustrations in the documentation and I'll surely go back to circleci for my CI :/

[edmundsj]

Would really like this functionality to be in place - I don't understand how it's possible to develop any sort of custom caching without this functionality. This would save us a tremendous amount of time and sanity.

Also got this error when trying to define job-level env-vars in terms of other job-level env-vars:

  acme-bundle:
    runs-on: ubuntu-20.04
    needs: build
    env:
      # if triggered from a branch containing /, use "wip", otherwise tag name
      version: ${{ contains(github.ref_name, '/') && 'wip' || github.ref_name }}
      fullfilename: acme-${{ env.version }}.${{ github.sha }}.bundle
    steps:
      ...
      - name: Pack
        run: tar -czf $fullfilename --format posix -C DIST .
      - name: Upload
        run: aws s3 cp $fullfilename s3://$BUCKET/ACME/$version/$fullfilename

— by GH Actions rules, the definition of env.fullfilename is forbidden to use env.version on the previous line 🤦‍♂️

The workflow is not valid. .github/workflows/release.yml (Line: 190, Col: 21): Unrecognized named-value: 'env'. Located at position 1 within expression: env.version

---

Instead of trying to untangle the truckload of flavors of "a variable" 🙄 from GH Actions docs (vars definable on 5 nesting levels, env vars with 3 nesting levels, contexts... oh my!) — just use the shell.

Shell variables (and "actions" BTW too) are simple enough:

  acme-bundle:
    runs-on: ubuntu-20.04
    needs: build
    # NOTE the job-level `env` yaml is useless https://github.com/actions/runner/issues/1189
    steps:
      - name: Format acme-bundle filename
        run: |
          # if triggered from a branch containing /, use "wip", otherwise tag name
          version="${{ contains(github.ref_name, '/') && 'wip' || github.ref_name }}"
          fullfilename="acme-${version}.${GITHUB_SHA}.bundle"
          { echo "version=$version"
            echo "fullfilename=$fullfilename"
          } >> $GITHUB_ENV
      ...
      - name: Pack
        run: tar -czf $fullfilename --format posix -C DIST .
      - name: Upload
        run: aws s3 cp $fullfilename s3://$BUCKET/ACME/$version/$fullfilename

env is also not usable within a job which uses a shared workflow, within the with block e.g.:

env:
  MY_ENV: test
jobs:
  some-job:
    uses: Org/repo/path/to/workflow.yml@master
    with:
      some-input: ${{ env.MY_ENV }}

[Twipped]

I just got bit by this, not with env, but with vars. And yes, it appears to be an odd edgecase of failed support in reusable workflows around passing inputs to actions. We have an organization level variable of NODE_VERSION that we cannot use in any of our workflows. It produces the error Unrecognized named-value: 'vars'. Located at position 1 within expression: vars.NODE_VERSION

env is also not usable within a job which uses a shared workflow, within the with block e.g.:

Oh what the...why github actions have to be so much worse and immature compared to the gitlab.

Now I have to rewrite everything again, great idea of using env: for global constants goes to the dumpster.

env is also not usable within a job which uses a shared workflow, within the with block e.g.:

Well, to a poor soul that stumbles upon this issue, I have a solution (crutch-lution?) for the crutch-full github actions system.

The idea is to convert env: to outputs and they for whatever unholy reason 🔯 can be used in the with for workflow call.

With that idea in mind the abomination was created:

env:
  # Global vars
  YOUR_VAR_1: 'whatever value you want to pass'
  YOUR_VAR_2: rc.${{ github.sha }}-whatever

jobs:
  github_sucks:
    runs-on: ubuntu-latest
    outputs:
      YOUR_VAR_1: ${{ steps.blah.outputs.YOUR_VAR_1 }}
      YOUR_VAR_2: ${{ steps.blah.outputs.YOUR_VAR_2 }}
    steps:
      - id: blah
        run: |
          vars="
          YOUR_VAR_1
          YOUR_VAR_2
          "
          setOutput() {
            echo "${1}=${!1}" >> "${GITHUB_OUTPUT}"
          }
          for name in $vars; do
            setOutput $name
          done

  build:
    needs: [ <actual dependencies> , github_sucks ]
    uses: ./.github/workflows/build_action.yml
    secrets: inherit
    with:
      whatever_input_1: ${{ needs.github_sucks.outputs.YOUR_VAR_1 }}
      whatever_input_2: ${{ needs.github_sucks.outputs.YOUR_VAR_2 }}

The big downside, beside this being a very big crutch, is that you have to hardcode the variable names in the converter job.
I did not found a sane way to even get the list of env keys, you could use ${{ toJSON(env) }} and parse it in the run via jq or something similar but it would be adding more salt to the wound.

For anyone that ended up here because it's the first result on google and you're having issues with using env in with then see this other open issue (which still has no resolution but at least it isn't closed and hasn't been linked here before) #2372

[anajuliabit]

I can't believe that three years later, and with so many complaints, github has not fixed this yet.

[kamzil]

Closed, but not fixed.

[Kamforka]

Guys, it's not github anymore, it's microsoft and we relive the same nightmare here what was before called Azure DevOps...
