Why does sql error 23506 occur?

Question

Java

Good afternoon
The situation is as follows I
added the H2 database for the test
The test passed, everything worked
The next time I tried to add the ResponseStatus, an SQL error 23506 appeared

I can’t understand why this happened

Answer 1

This is more likely a database error, not a Java one.
Perhaps the data that you require to update or add is missing in the associated table.
