I don't know what todo with these psalm errors. they don't make sense to me.

It looks like this method never returned a list<string>, because array_unique might return a array with holes (which contradics the list type)

You need to wrap it with array_values(array_unique(…)), this gets rid of potential holes and is usually accepted by psalm & friends.

yes, but that would change the logic of the function. I am not sure the types are wrong or the implementation :).
(and I don't want to add even more function calls. I try to get rid of everything which is too much)

I had a closer look at the logic involved and the callers. it seems the callers don't need a list and fixing the types also fixes some baseline errors. I think thats the way to go.
