Answer 1

This can be solved bby many ways :

1 To fix this error, delete the latest migration file ( a python file) then try to perform a migration afresh.

If issue still persists try these commands :

$ flask db stamp head  # To set the revision in the database to the head, without performing any migrations. You can change head to the required change you want.
$ flask db migrate     # To detect automatically all the changes.
$ flask db upgrade     # To apply all the changes.
