Symfony DI container returns its config as ArrayObject which blocks doing anything with mezzio

Setup a mezzio skeleton with Symfony DI container and added swoole support (maybe not required).
As I liked to test this setup with ./vendor/bin/laminas -v mezzio:swoole:start one typical error message popped up

Expected map - associative array with string keys.

It turned out that the Assert class checks for is_array whereas SyDI return ArrayObjects as it configs, currently not knowing which side is behaving wrong but assume that this combination was not tested yet.

Is there any option where I can change anything to get it work?
