Google cloud logging python script permission error

Hi I am trying to write a python script that does exactly what the following command does:

gcloud logging read "logName=projects/[project_name]/logs/[id]"

so when i run that command from the cli it does not give me any error, it outputs the logs as expected.

however when i run my python script:

import argparse
import datetime  
import os
import sys
from pprint import pprint

from google.cloud import bigquery
from google.cloud import logging

assert "GOOGLE_APPLICATION_CREDENTIALS" in os.environ

def main():
    client = logging.Client()
    log_name = 'log_id'
    logger = client.logger(log_name)
    for entry in logger.list_entries():
        print(entry.payload)


if __name__ == "__main__":
    main()

I get the error: google.api_core.exceptions.PermissionDenied: 403 The caller does not have permission

Im not sure what to do here, since the command line runs, i clearly have permission. any thoughts would be greatly appreciated
