It seems like $params defined by parameter $params on line 16 can also be of type null; however, Sichikawa\LaravelSendgri...er\SendGrid::sgEncode() does only seem to accept array, maybe add an additional type check?
This check looks at variables that have been passed in as parameters and are passed out again
to other methods.
If the outgoing method call has stricter type requirements than the method itself, an issue is raised.
