File upload does not work with altair

[Selectorrr]

Here is an example

This is an example request:

Error in console:

But with curl is worked!
curl localhost:8081/graphql \ -F operations='{ "query": "mutation ($file: Upload!) { singleUpload(file: $file)}", "variables": { "file": null } }' \ -F map='{ "0": ["variables.file"] }' \ -F [email protected]

[oliemansm]

Isn't this a problem of altair itself though? This lib only provides an easy means of exposing altair.

[cescoferraro]

@oliemansm the error @Selectorrr is having is due to setting the Content-Type header as application/json. I can replicate this here.But then I bump into the another error.
Which is described here

curling get me the same result also

curl 127.0.0.1:8080/graphql -F operations='{ "query": "mutation ($file: Upload!) { uploadFile(file: $file)}", "variables": { "file": null } }' -F map='{ "0": ["variables.file"] }' -F [email protected] curl 127.0.0.1:8080/graphql -F operations='{ "query": "mutation ($file: Upload!) { uploadFile(file: $file)}", "variables": { "file": null } }' -F map='{ "0": ["variables.file"] }' -F [email protected]

[oliemansm]

I've just tried this too and indeed Altair is sending the wrong Content-Type, i.e. application/json. So that confirms my original triage that this is not a problem caused by our library, but is a problem with Altair.

Have you checked their repo if there are known issues? Or perhaps it's already solved in a more recent version of Altair, which you could load using the cdn setting.

[oliemansm]

Apparently the AltairController was setting the accept and content-type headers explicitly to application/json. No idea why. I removed that now for the 7.1.0 release. You'll have to clear you localStorage before it'll take effect though.
