"Auth header must be a string" - httpservice?

Hello, I am trying to update a github file with httpservice, and github requires two authorization parameters: <username> and <token>.

If I try to use a table as the auth header it errors saying it must be a string, and I need to provide two strings using a table.

Headers = { ["auth"] = { "Username", "API Token" }, ["Content-Type"] = "application/json", },
