Required 'Alpha Access' permission for 'Compute API' while adding additional disk on a VM instance

Question

After adding additional disk on a VM instance, I got a "Required 'Alpha Access' permission for 'Compute API'" error when clicking save.

Does anybody know what causes this error and how to solve this issue?

What you're experiencing is a bug. I've found this thread on Google Issuetracker - it looks like Google Engineers already know about it and working on solving it - you can add your email to a CC list or post description of your case there.

If you do this you will be updated as soon as the fix will be rolled out to production.
