Cannot get custom backgrounds to work

[tomk3003]

I tested that my webserver is serving the config.json and the images successfully.
I can see in the webserver's access log that the config.json is fetched from the server on Teams start
and an empty thumbnail with the correct name is shown in the background list.
But Teams does not try to fetch either the image or the thumbnail.

How can I debug this further?

[tomk3003]

I can see that a file named custom_bg_remote.json is created in the config directory.
But the values in src and thumb_src are prefixed with /teams-for-linux/custom-bg.

[{"filetype":"jpg","id":"cbg001","name":"Grand Canyon 01","src":"/teams-for-linux/custom-bg/1050608.jpg","thumb_src":"/teams-for-linux/custom-bg/1050608_thumb.jpg"}]

@tomk3003 I just got this to work after beating on it a while. I couldn't get it to work with a remote Apache instance but I was able to get it to work with a local one. This is my config.json:
╰─➤ cat config.json
{
"customBGServiceBaseUrl": "http://127.0.0.1",
"customBGServiceConfigFetchInterval": 0
}

The biggest clue that helped me was you mentioned that custom_bg_remote.json was getting written and like you mentioned it had prefixed the paths with "/teams-for-linux/custom-bg" .

What fixed it for me was creating that path on my filesystem (not under the apache2 DocumentRoot), so now I have /teams-for-linux/custom-bg/backgrounds -> /var/www/html/backgrounds/. I think whoever developed this feature for the program tested with this setup on their workstation and the program may have some references to it.

I do not understand this at all. I can see the request in the nginx access log from this morning, but without having made any changes I cannot get teams to request it again. Without this, debugging makes no sense because there is nothing to debug. I am short on time at the moment. I hope I'll find time on the weekend.

Ok, the first thing to look at would be why the request to the Webserver is only done once a day at the first teams startup. After that no request is sent at all. Despite having set customBGServiceConfigFetchInterval to 10. Here is my config.json

{
    "closeAppOnCross": true,
    "disableAutogain": true,
    "disableMeetingNotifications": true,
    "customBGServiceBaseUrl": "https://ghost/Pictures/Backgrounds",
    "customBGServiceConfigFetchInterval": 10
}  

I cannot see anything related to my webserver in the console or the network tab of the debugger.
It does not appear under Remote Addr

The fetch happens when you launch the application. You must open debug and see what happens in console and network when you're at custom backgrounds page in teams. Like you need to check what happens when you turn on camera before joining a meeting and click on background effects. You'll see a list to the right with images. At that time what is displayed in the console and network will help you understand what is happening.

I have used http without enncryption and looked at the communication with Wireshark to see what's going on.
There is only one connect from the client to my webserver fetching the config.json file successfully and absolutely nothing after that.
Not a single TCP request. No wonder I can't find anything in the debugger of the application.
Funny is, that the custom_bg_remote.json in the .config directory gets rewritten every 10 seconds (=customBGServiceConfigFetchInterval).
I cannot think of any more I could do to narrow this down.

[tomk3003]

By the way: setting customBGServiceIgnoreMSDefaults has no effect. The default backgrounds are shown anyway.

We have released a new version that works for teamsv2 under https://github.com/IsmaelMartinez/teams-for-linux/releases/tag/v1.4.36 (do check the docs as there are a few changes and is now disabled by default). Check if that works for you
