@mammoth-bear-12532 We were testing the ability to add a new entity type by using a custom repository and we ran into an exception that tell us that adding a new entity type that way is not supported. You told us earlier that this should be possible, but it doesn't seem to be. FWIW I can see from the commit history that
you were the one that added the exception logic. Does this check just need to be removed, or is there some other piece of the puzzle missing? If it can be removed, I can try making the change and sending a pull request.
