I hit this too with snapcraft 2.35 and upload of the second version of a very large snap (~600M), the patch in comment #1 worked for me too.

[Olivier Tilloy (osomon)]

The attached patch fixes the issue for me too. Had been hitting the error quite a few times when uploading deltas for the libreoffice snap, which weighs ~400MB.
