After a clone, importing unpublished changes for a scoped application (ABC) from an external repository (like git) throws the below error:

"Application 'ABC' is already associated with another repository configuration"

All releases

There exists an older repository configuration for the app on sys_repo_config table.

1. Delete the old config record in "sys_repo_config" table for the application.

2. Open the application in Studio.

3. Navigate to Source Control > Link to Source Control.

4. Enter the proper config/credentials to link to the repository and click Submit.
