Running Alice Faber Demo locally on Ubuntu 18.04, FAILING!

I am following instructions from this read.md https://github.com/hyperledger/aries-cloudagent-python/blob/master/demo/README.md#running-locally.

Any help from here would be grateful.

[adityaishan]

I got it working....

[swcurran]

Awesome. Sorry for the lack of response. It was tough to figure out what was happening from the info.

Any info on what you changed to make it work?

[Sarangc1203]

Just putting this out here for others who face a similar issue.
@swcurran Seems like the error was with configuring the ledger. Somehow location of the genesis file was incorrect and hence server.anchor.AnchorException: No genesis file or URL defined error in the VON's log. I haven't personally tried running it locally, but I faced a similar issue when I used their docker script to run the demo. But the error was that I hadn't copied the genesis file into the docker container. Also, there was some error in specifying the location to the genesis file (I had used a relative path initially) as the pwd changed when the container starts.

[swcurran]

I'll give a try on mine again. It's worked in the past but haven't run it in awhile. I'm Ubuntu 18.04 as well so hopefully will see consistency.

Had the same issue while following the tutorials.

https://github.com/hyperledger/aries-cloudagent-python/tree/master/demo#running-in-docker

I ran the command under the running in docker section, and received the error

Tried to run the same command of "Running in a browser" section and everything worked.

LEDGER_URL=http://dev.greenlight.bcovrin.vonx.io ./run_demo faber

Hope that can help others.

Thank You @rodolfoleal

The exact cause is that the seed is not registered to the localhost ledger which by default the demo searches for localhost.

To overcome this issue:

1. Navigate to http://localhost:9000 if that is where your indy ledger is
2. Add the following details to the ledger depending on the data on the console log displayed, the agent seed in this thread was 'd_000000000000000000000000994455', it will be different for you, mine was

You could try using indy-cli to add a DID to the ledger as well although I have not tried.

Thereafter the demo will be able to ./run_demo faber

[swcurran]

That’s not right @dnaicker86. There is a DID that has a well known seed written on the ledger, and that DID is used to create the other objects, so no new seed/DID is needed. You can add them and specify the seed/DID is the one you want to use, but you don’t have to. The same well known seed is used for all sandbox Indy networks.

[dnaicker86]

It worked for me and resolved the issue. I think the documentation and tutorials need to be clarified as these errors still persist and developers need to try and make sense of them instead of them being told it is not right when they have to resolve on their own.
