Typescript error for part param in youtube API

[angelhodar]

1. Is this a client library issue or a product issue?
   Client library issue

2. Did someone already solve this?
   No as I have seen

Environment details

Here I share a minimal codesandbox where you can see the ts warning: https://codesandbox.io/s/quirky-pascal-dhvsxt?file=/src/index.ts I have also tried to pass the parameter as a list of strings but it doesnt fix the issue either.
