tSQL to set up user with View Definition permission on SQL Azure

This will not work on sql azure. You will need to grant view definition at the database level. (without the ANY keyword)

GRANT VIEW DEFINITION TO gu6t6rdb

P.S: I hit the exact same issue and this seemed to solve my problem. I also had to do a Grant Execute (but it depends on what your bacpac is applying to the database)

Got it. I can add the user to the db_owner role and then the export proceeds without error.

EXEC sp_addrolemember 'db_owner', 'gu6t6rdb'
