The application suddenly becomes unable to log in with an error

[松島一郎]

An application that used GAE suddenly became unable to log in with the following error:

com.google.appengine.api.datastore.DatastoreFailureException: Missing or insufficient permissions.

With local debugging, it works. Even if I debloy again, I get an error.

How can I solve it?

Hi,

If the issue still persists, I recommend to create a PRIVATE Issue Tracker and provide us with your project id there so that we would be able to dig into the issue.
