I created a virtual entity in dev environment and exported our solution as a manged solution. the first update of our solution in the test environment worked without a problem. virtual entity was created, all good.

but since then I am not able to update our solution in test. I always get this error Message:

Solution import Failed. Error: An entity with the specified name <my_entity_name> already exists for data source - 9dbd9482-3636-ec11-b27f-005056872fc1. Please specify a new external name.

Any ideas how to fix this? Thanks
