Hi Felix,

the error message refers to member sender of entity ChatMessage. I looked up the constraint in my database and there it says:


  | CONSTRAINT fk278c74e4b6f3dc65 FOREIGN KEY (sender)
  |       REFERENCES users (id) MATCH SIMPLE
  |       ON UPDATE NO ACTION ON DELETE NO ACTION,
  | 

I wonder about "ON DELETE NO ACTION". Shouldn't it be "ON DELETE CASCADE"?
