launch URL is beheaving wrong on gitlab instance, but not on github.

[arm2arm]

Dear Developers, we have following problem: same reana.yaml doesnot run hosted on different git repos.

1. URL giving error: An error has occurred Cannot handle given URL
   https://reanadev2.aip.de:30443/launch?url=https://gitlab.aip.de/akhalatyan/reanademo
   same error with branches:
   https://reanadev2.aip.de:30443/launch?url=https://gitlab.aip.de/akhalatyan/reanademo/-/tree/tester
   but URL: https://reanadev2.aip.de:30443/launch?url=https://gitlab.aip.de/akhalatyan/reanademo.git
   running as expected.

digging more in logs we can see:

2024-11-11 16:06:58,648 | root | uWSGIWorker4Core3 | ERROR | Traceback (most recent call last):
  File "/code/./reana_server/rest/launch.py", line 167, in launch
    fetcher = get_fetcher(url, tmpdir, specification)
  File "/code/./reana_server/fetcher.py", line 514, in get_fetcher
    raise ValueError("Cannot handle given URL")
ValueError: Cannot handle given URL

2. the same reana.yaml hosted on github.com working without problems with tree or commint hash
   Works as expected: https://reanadev2.aip.de:30443/launch?url=https://github.com/arm2arm/reana-demo/tree/tester

current server image: reanahub/reana-server:0.9.5-alpha.2

Any assistance would be greatly appreciated. Thank you!

Hello @arm2arm ,

The GitLab instances allowed to be used with the launcher are:

• gitlab.com
• gitlab.cern.ch
• the instance set as secrets.gitlab.REANA_GITLAB_HOST

What value is set as secrets.gitlab.REANA_GITLAB_HOST in the Helm values? Could you double check whether it is set to gitlab.aip.de?

Question: do you need to support more than one additional GitLab instances, other than gitlab.com and gitlab.cern.ch?
