That log helps. This was working a while back. I wonder if something new broke. I'll try testing it again.

[amir20]

Great. I was able to reproduce this. I'll see what I could be the problem. Something must have changed.

Looks like I wasn't handeling errors correctly. @jenggo can you test amir20/dozzle:pr-3311. I'll merge when you let me know it works. It worked with my testing.
