Could it be that one of the CDTs use a deleted data type?
What is CDTThe database is imported from other environments
How should I check if a data type that has been deleted is used
How much experience do you have with Appian?
What do you mean with "The database is imported from other environments"? And, does that "import" also include all required Appian objects?
New to Appianimport refers to the database level. That is mysql data
Got it.
Then we need to go back to the import of Appian objects. Are all required objects imported? My interpretation is, that the datastore refers to an Appian Data Type (CDT) that is not available. Hence it cannot check the DB schema.
Compared with the dev environment, the datastore table is exactly the same.same for mysql table
This is not about the DB. You need to check your Appian objects.

Without any Appian knowledge, this will become difficult. I suggest to first attend the Appian trainings and get some experience with how Appian works. Then come back to this issue and try to solve it.
