$this->mockServiceProvider of type null is incompatible with the type Yiisoft\Yii\Testing\MockServiceProvider expected by parameter $mockServiceProvider of Yiisoft\Yii\Testing\FunctionalTester::fillDefaultMocks().

The expression return $this->mockServiceProvider could return the type null which is incompatible with the type-hinted return Yiisoft\Yii\Testing\MockServiceProvider. Consider adding an additional type-check to rule them out.
