Binding to a callable that accepts array as an argument fails with "Invalid type in function '...' Cannot convert argument 1 from Callable to Array"

Issue description

I can't bind arguments to a callable that accepts single array as argument

Steps to reproduce

Make this code run:

    func _ready() -> void:
        var callable: Callable = test.bind(["one", "two", "three"])
        callable.call()

    func test(arr: Array[String]) -> void:
        for e in arr:
            print(e)

It will fail with the error like Invalid type in function '...' Cannot convert argument 1 from Callable to Array

This is specifically for Array[String] and that the passed argument isn't an Array[String] but just an Array, if you use:

    func _ready() -> void:
        var arr : Array[String] = ["one", "two", "three"]
        var callable: Callable = test.bind(arr)
        callable.call()

    func test(arr: Array[String]) -> void:
        for e in arr:
            print(e)

It works, this is related to general issues with typed arrays, unsure what the specific error is here, the "Callable to Array" is likely a separate issue with how the error printing is done

Thank you very much 🐳 My issue is solved now. Feel free to close this issue or keep it open / create a new one for the error printing

It's still an issue that it doesn't handle the conversion properly, even without the weirdness of the error message, might already be reported though

Same core issue as #91048, Packed Arrays do not coerce to typed arrays, only to Array.

func _ready():
    var callableOK: Callable = TestOK.bind(["one", "two", "three"])
    callableOK.call()

    #var callableProblem: Callable = TestProblem.bind(["one", "two", "three"])
    #callableProblem.call()

func TestProblem(arr: Array[String]) -> void:
    print("TestProblem arr: %s" % arr)

func TestOK(arr: PackedStringArray) -> void:
    print("TestOK arr: %s" % arr)
