Symfony Expected argument of type "string", "null" given
In Symfony, if you encounter an error message stating "Expected argument of type 'string', 'null' given", it means that you are passing a null
value instead of a string where a string is expected.
To resolve this issue, you need to make sure that you are passing a valid string value instead of null
to the function or method that requires it. You can do this by checking if the value is null
before passing it, and handle the situation accordingly.
