I'm having this error in my laravel system: 

cannot add or update a child row a foreign key constraint fails laravel

It informs you that the ID does not exist, only that it exists. Even when I try to perform the insertion manually this error is displayed.

From a select in your tbl_respuestas table and see if the fields search_id, question_id and option_id are not 0.

If yes, change to null and try again.
