betodealmeida opened a new issue #11028:
URL: https://github.com/apache/incubator-superset/issues/11028
When importing a dashboard from the `examples` database to a database with a
different name, the import fails.
### Expected results
Import should complete.
### Actual results
```
sqlalchemy.exc.InvalidRequestError: This Session's transaction has been
rolled back due to a previous exception during flush. To begin a new
transaction with this Session, first issue Session.rollback(). Original
exception was: (sqlite3.IntegrityError) UNIQUE constraint failed:

#### How to reproduce the bug
0. Set `PREVENT_UNSAFE_DB_CONNECTIONS` to false.
1. Create a new database called `examples 2`, using the same SQLAlchemy
connection string as the `examples` database.
2. Export the "Unicode test" dashboard from `examples`.
3. Import the dashboard into the `examples 2` database.
