Group avatar - file format not supported issue

[trafford-tbe]

Description of the problem, including code/CLI snippet

I'm trying to add avatar to group using following command:

gitlab -v group create --name "Test 1" --path "test1" --parent-id 21 --avatar "/tmp/logo_lab.png"

where:

1. Group creation without --avatar option works correctly.
2. Path to .png is absulute path to file with correct read permissions.
3. The same file added using web-gui dispalys correctly.

Expected Behavior

Avatar added to group.

Actual Behavior

Message returned:
Impossible to create object (400: Failed to save group {:avatar=>["file format is not supported. Please try one of the following supported formats: image/png, image/jpeg, image/gif, image/bmp, image/tiff, image/vnd.microsoft.icon"]})

I think you will need to do something like: https://python-gitlab.readthedocs.io/en/main/cli-usage.html#reading-values-from-files

gitlab -v group create --name "Test 1" --path "test1" --parent-id 21 --avatar "@/tmp/logo_lab.png"

Already tested with following results:
'utf-8' codec can't decode byte 0x89 in position 0: invalid start byte
which seems to be answer from python.

Ah. The code for the @ prefix assumes it is a text file :(

So at the moment I don't think it can be done via the CLI. With the API it can be done.

Yes. I made it with cURL, but tried to use one module for Ansible:
https://docs.ansible.com/ansible/latest/collections/community/general/gitlab_group_module.html
Nevertheless, thank you for confirmation, but does this mean we have an issue now?

I have created an issue #2752 to track it. I don't have an ETA on when someone will volunteer to work on it.
