I'm trying to implement nifi custom processor for google api client via python. However, while importing the libraries, I was getting the Attribute error: @Matt Burgess ExecuteScript[id=b76c919f-015f-1000-c240-f0d0ade570c2] Failed to process session due to org.apache.nifi.processor.exception.ProcessException: javax.script.ScriptException: AttributeError: 'module' object has no attribute 'DEFAULT_MAX_REDIRECTS' in <script> at line number 23: javax.script.ScriptException: AttributeError: 'module' object has no attribute 'DEFAULT_MAX_REDIRECTS' in <script> at line number 23 Libaries to Import in the code: sys.path.append('/usr/local/lib/python3.6/site-packages/googleapiclient') sys.path.append( '/usr/local/lib/python3.6/site-packages/google_api_python_client-1.6.4.dist-info') sys.path.append( '/usr/local/lib/python3.6/site-packages/google_apputils-0.4.2-py3.6-nspkg.pth') sys.path.append( '/usr/local/lib/python3.6/site-packages/google_apputils-0.4.2.dist-info') sys.path.append('/usr/local/lib/python3.6/site-packages/oauth2client') sys.path.append( '/usr/local/lib/python3.6/site-packages/oauth2client-4.1.2.dist-info') sys.path.append('/usr/local/lib/python3.6/site-packages/oauthlib') sys.path.append( '/usr/local/lib/python3.6/site-packages/oauthlib-2.0.6-py3.6.egg-info') from datetime import datetime, timedelta, date from googleapiclient.errors import HttpError from googleapiclient.discovery import build from oauth2client.client import AccessTokenRefreshError from oauth2client.service_account import ServiceAccountCredentials Note: I'm using the executor script with Python.
