Cant register user Backendless encountered an error while handling the request

I`m trying to register users with rest API but response from my post is 500 internal server error : Backendless encountered an error while handling the request. An internal trouble ticket with ID 5BC5831C-03B1-227C-FFD3-FF3D1A977700 has been created and we will be investigating the issue.
org.hibernate.exception.SQLGrammarException: could not extract ResultSet and 140 rows more.

This is the application id: F1AE6890-23E9-EBF9-FF92-0C1239F31F00
This is the rest api key: 604BD08E-0119-4F06-BA42-589E2AC04488
This is the address for request:

The headers have content-type: application/json.
The body of request is { “email”: “email@xxx.xx”, “password”: “123456” }
I`m sending the request with postman just to try the functionality but its not working at all.
