Snap failed to upload "__len__() should return >= 0"

I have a snap which builds in the snapcraft build service, but today it’s failing to upload.

Here is the build log

Here’s what it looks like on launchpad.


I can’t press “Retry” because I don’t have permission. But I can trigger a rebuild, which is a waste of time and resources.

Triggering again failed again.

Yeah, been hitting this also. Bug raised here and is being worked on:

is that your null snap ? :smiley:
