[ralphlaude]

It was the same error I had locally. I have nothing to add. Let the fix for #20 and see how it works.

[sleipnir]

@ralphlaude your error message was slightly different from the message reported by @marcellanz test.
What I need to know about you are the versions that are using the protocol and how I can reproduce the error locally, which image used in your tests and etc ...
It would help me a lot.

[ralphlaude]

Sorry :) @sleipnir to be late with the error-log. I hope it can help.

[sleipnir]

Thanks @ralphlaude can you report what the proxy tested against? I'm interested on the User Function side, it was a docker image that I can download, it was a branch of some repository, what version of the protocol is used by this user function, and etc ...?
How can I reproduce your test faithfully to get to the same error?

[ralphlaude]

@sleipnir locally I ran only the following commands:

1. iex --name [email protected] -S mix
2. iex --name [email protected]
3. iex --name [email protected]

I didn't start a docker image. If you just run all the following commands you can reproduce the errors. I would like to help more.

[sleipnir]

So there is no error, this message is normal because no user role was found. I'm closing this issue.
Thanks @ralphlaude
