Import fails if a referenced user already exists

Tested on Drupal 10.2 with php 8.2 and works correctly. Can you give more feedback in order to reproduce the issue? Can you reproduce it on a clean environment?

Yes. The issue is that the uuid of the admin user is different between instances, so it tries to create a new user with the same name. So I guess I could just update the uuid to reflect the admin on the separate instance. Just a minor inconvenience.

I am trying to use this to generate default content for a distribution though. I could write a script that gets the uuid of the admin, updates the uuid in each default content zip, and then imports. But I guess the alternative is whether the import needs to respect the uuid of the referenced user, or if it could just infer that information based on the user with the given username. Any different ideas or suggestions?

Maybe a big ask but a token would be cool

I think this should be improved in doImport() method, at least we can have an extra validation by loading users by email and username if entity by uuid was not found. I will provide a patch, once it's available, there will be nothing to do on your side, I'm also planning to provide a new release soon, so the patch will be included to the new release immediately
