Hi,

We are using the REST API with BaseX 7.6. After doing approximately 100 PUT requests for creating documents in a database, we get the error listed below. So far I haven’t been able to reproduce it, but I have the database if that would be any help. Any suggestion on how to un-corrupt the database?

Improper use? Potential bug? Your feedback is welcome:
