500 internal server error when creating a new project (and other issues).

[ScionOfDesign]

Hey, I've been very interested in integrating Taiga with Keycloak. This plugin seems to work initially, but it runs into some issues as I try to use it. To preface, this is all set up following the instructions step-by-step, and these issues do not occur when using taigaio/taiga-back:latest and only when robrotheram/taiga-back-openid:latest is used.

• First of all, the very first time I try to login with Keycloak, it redirects me properly but when I get back to Taiga it just loads until I get a gateway error. Clicking login again, however, works.
• The second issue is that an error is thrown if the 'Full Name' from Keycloak is null. I think instead it should use the 'preferred_username' falling back to the 'full_name', and finally falling to the 'username'.
• The primary issue is that creating a new project, or creating an epic in an existing project, results in an internal server error. This is the error that occurs in taiga-back when I try to make a new project:

  
  ERROR:2021-03-05 11:52:29,937: Internal Server Error: /api/v1/projects

Traceback (most recent call last):

(authdata, host) = parse_result.netloc.split("@")

ValueError: not enough values to unpack (expected 2, got 1)

The above exception was the direct cause of the following exception:

Hi sorry for the late reply, that error log looks like its got nothing to do with the plug-in, is complain about rabbit I seems that the Rabbit config is incorrect.

I am not sure what is causing the gateway error. It might be also related to Rabbitmq errors

However I will look at the :

The second issue is that an error is thrown if the 'Full Name' from Keycloak is null. I think instead it should use the 'preferred_username' falling back to the 'full_name', and finally falling to the 'username'.

I too am seeing the exact same behaviour on a freshly deployed Taiga docker with this plugin. I found this, which seems to imply that it was a bug resolved by taiga on the 24th Feb: https://tree.taiga.io/project/taiga/issue/4336

[niklashagman]

Am having the same problem on a new installation of Taiga. Docker containers from taiga works. Docker containers from robrotheram do not.

[robrotheram]

This should now be fixed. The containers are now build to the latest taiga release and specific releases. Fallback for usernames has been implemented as well as some mapping customizations that can be applied.

I am closing this issue but if there are further issues then please open another issue

[niklashagman]

Yep, works great now. Thanks!
