Cannot add or update a child row: a foreign key constraint fails

[Lopastudio]

I made this API acording to the tutorial, and after starting it up, I started getting this error:
Cannot add or update a child row: a foreign key constraint fails (ne028304db.user_roles, CONSTRAINT user_roles_ibfk_1 FOREIGN KEY (roleId) REFERENCES roles (id) ON DELETE CASCADE ON UPDATE CASCADE)
It only occurs when I try to register and the api crashes.
Here is a full error:

node:internal/process/promises:288
            triggerUncaughtException(err, true /* fromPromise */);
            ^
