Local File List for Project 'XY' empty

[meyerlor]

I'm playing around with a self hosted instance of QfieldCloud - i got it working as far as i can tell, i can login to the django interface and with QfieldSync i can upload a project.
Although when i want to download that said project in Qfield, i always get a "File Not Found" error:

Via the admin interface i can check, all the files are there - any idea, in which direction i could investigate? Maybe an MinIO issue?

Update: After the initial upload to the cloud, i have to save the project once more and upload the .qgs file again, that makes it work then. Somehow the cloud seems not to wait until the initial upload is finished when calling the worker i guess.

It would be interesting to know what is the list of files returned from the remote. Whatever is the issue, should be somewhere around this snippet:
