[Python] Python injector doesn't work for NewType based on tuple[str, str]

I'm trying to use https://github.com/python-injector/injector to inject a tuple[str, str], but it doesn't work.

import injector
from typing import NewType

Foo = NewType("Foo", tuple[str, str])


class MyModule(injector.Module):
def configure(self, binder: injector.Binder) -> None:
binder.bind(Foo, Foo(("x", "y")))


injector.Injector(modules=[MyModule]).get(Foo)


leads to error

I've been injecting NewType('Bar', str) many times and they all work, so it has to be due to something special related to tuple. I wonder if anyone has insights into why.
