Hi @FadlyKnight,
Thank you for posting to the Community! I understand that you are receiving a Validation Error when trying to search files using the API.
I want to tag in some of our Top Contributors to see if they have experienced this before. Hi @Gonzalo @ChristinaKay and @Teun have any of you seen this error before? If so, how did you resolve it?

It’s a bit confusing the API works when using one private token, but doesn’t work when using another private token. Both tokens have the files scope permission.
