It seems like $configuration defined by parameter $configuration on line 16 can be null; however, SimpleSAML\Module\monito...ory::setConfiguration() does not accept null, maybe add an additional type check?
It seems like you allow that null is being passed for a parameter, however the
function which is called does not seem to accept null.
We recommend to add an additional type check (or disallow null for the parameter):
functionnotNullable(stdClass$x){}// UnsafefunctionwithoutCheck(stdClass$x=null){notNullable($x);}// Safe - Alternative 1: Adding Additional Type-CheckfunctionwithCheck(stdClass$x=null){if($xinstanceofstdClass){notNullable($x);}}// Safe - Alternative 2: Changing ParameterfunctionwithNonNullableParam(stdClass$x){notNullable($x);}
This check looks for
@paramannotations where the type inferred by our type inference engine differs from the declared type.It makes a suggestion as to what type it considers more descriptive.
Most often this is a case of a parameter that can be null in addition to its declared types.
