401: Unauthorized when calling apps.list_installations

It looks like endpoints that require JWT tokens do not work.

I've verified the jwt token is valid by creating an access token via the github api.

Below is my code:

import time
import jwt

from ghapi.all import GhApi
import requests

private_key = """-----BEGIN RSA PRIVATE KEY-----"""
app_id = 1
installation_id = 1

def create_jwt(key, id, expiration=60):
    """
    Creates a signed JWT, valid for 60 seconds by default.
    The expiration can be extended beyond this, to a maximum of 600 seconds.
    :param expiration: int
    :return string:
    """
    now = int(time.time())
    payload = {"iat": now, "exp": now + expiration, "iss": id}
    encrypted = jwt.encode(payload, key=key, algorithm="RS256")

    if isinstance(encrypted, bytes):
        encrypted = encrypted.decode("utf-8")
    return encrypted

api = GhApi(token=create_jwt(key=private_key, id=app_id))

api.apps.list_installations()

returns
