Executing start did not succeed: result: 3, message: The database has to be updated.
While trying to run my app in the cloud for the first time, I ran into this error preventing deployment: “Executing start did not succeed: result: 3, message: The database has to be updated.” I’d be happy to indulge but I don’t know what that means and what it entails… App runs fine locally.
It's a free app. I did find the cause of the problem in the log, though.
It was due to a unique constraint that was not unique! Basically, a validation rule that was defined twice in the model.
