It seems like new class { function __call($name, $args) { } } of type object<WebStream\Exception\Delegate\anonymous//Modules/Exception/Delegate/ExceptionDelegator.php$0> is incompatible with the declared type object<WebStream\Exception\Delegate\Logger> of property $logger.

It is generally recommended to explicitly declare the visibility for methods.
