The connection "{XXX}" is not found. This error is thrown by Connections collection when the specific connection element is not found.

Scenario

I had a few connections created in the Connection Managers in SSIS and all these connection configurations are stored in the Package Configurations. I just deleted a few unwanted connections from the Connection Managers and I got the following error with the package for every single deleted connection.

Error loading XXX.dtsx: The connection "{XXX}" is not found. This error is thrown by Connections collection when the specific connection element is not found.

Solution

Update your package configurations to reflect the changes made to the Connection Managers and the errors will be cleared automatically.
