defaultHeaders is being assigned to request.headers

[armoucar-neon]

There's an issue with the lib that makes defaultHeaders to be assigned to request.headers. It happens just after the execution of line 892 (dist code). When request.headers is undefined, then defaultHeaders is going to be assigned to request.headers because of how Object.assign works.

While debugging, we can check that after the execution of line 892:

This will lead to more bugs afterwards, because when logging the request.headers (which is defaultHeaders), the lib changes the 'Authorization' header value to [REDACTED], making this a default header that will override other 'Authorization' headers in subsequent calls.
