Package is in valid. Details: 'Could not unzip extension'

Question

Yesterday while trying to download another test version of my extension from Chrome web store, which had changes only in version number, I suddenly started to receive a strange error "Manifest file is invalid". I've spent all day searching the web for an answer to this problem, but didn't found anything useful.

Starting from this days morning error message had changed to: "Package is in valid. Details: 'Could not unzip extension'"

I've already tried thous variants:

1. zipping it with folder and without a folder
2. shortening zip file name
3. zipping it on mac and on windows
4. verifying zip file
5. uploding it with compression and without compression
6. searching for non-utf characters

Seems like chrome just throws thous errors randomly no matter what.

Answer 1

This has been fixed - try re-uploading and publishing again. Make sure to bump up your version number.
