Pullrequests have title 'None'

[MAGICCC]

Describe the issue

Somehow when I push the changes from Weblate to GitHub it will create a PR where the title is 'None' and without content.
I am not sure why it causes it.
See mailcow/mailcow-dockerized#4529, I edited the title manually and added the normal content as comment

I already tried

• I've read and searched the documentation.
• I've searched for similar issues in this repository.

Steps to reproduce the behavior

1. Add changes to weblate
2. Push to GH
3. It will create a PR with title 'None' and no content in the comment

Expected behavior

Have the 'normal' PR content.

Screenshots

Additional context

I updated to Weblate: 4.11.2 some days after release. Since we dont have so many translations I didnt see the issue immediately

[nijel]

It should be the first line of DEFAULT_PULL_MESSAGE, what do you have configured there?

This issue looks more like a support question than an issue. We strive to answer these reasonably fast, but purchasing the support subscription is not only more responsible and faster for your business but also makes Weblate stronger.

In case your question is already answered, making a donation is the right way to say thank you!

I never set a env varible in my docker-compose.override.yml for this so its empty

This happens to us as well, e.g. here tuskyapp/Tusky#2421
