Hello,

When i try to export my RSS feed on the web U.I the request failed and i have this following error in log :

Thanks for reporting, this sounds like Youtube tag does not have a colour associated.
Possibly because we forgot to normalize it to lowercase somewhere when saving it.
Looking into it.

Looks like MySQL now treats tags as case insensitive. It has originally been fixed by #625 but looks like it regressed in 5af5737.

In #1439, I have fixed what I think is the issue and new development build with the fix should be available shortly.

If you do not want to update yet, you can apply the following patch, which will omit the selfoss-specific color metadata when not available:

--- a/src/controllers/Opml/Export.php
+++ b/src/controllers/Opml/Export.php

             $this->writer->writeAttributeNS('selfoss', 'color', null, $tagColors[$tag]);
 
             foreach ($children as $source) {
