Unable to fetch app definition.

[Thuypham]

I have the trouble with my App. The notification like this:

Error
The app did not load
successfully. Please contact the app creator.
Unable to fetch app definition. Error: The added or subtracted value results in an un-representable Date Time. (Parameter months')

I have contact the Google Support Team. But the problem is still not resolved. I have regenerated the structure table, but without success. Have you ever encountered this problem? Please help me

As the message states you have a DateTime column that is attempting to be updated with a calculation that is invalid and does not result in a proper DateTime value.  You need to correct or remove that calculation.
