URL: https://github.com/apache/incubator-superset/issues/11620


   I have installed superset in AWS EC2 instance which is Ubuntu. It is working 
fine but i have a requirement to send dashboards in email to clients. I have 
configured SMPT, chrome browser, chromedriver, Redis and also made correct 
changes to config.py file. I am able to run celery worker, celery beat but if i 
try to send test email i am getting **UnboundLocalError: local variable 
'options' referenced before assignment** This is so frustrating in superset. 
Why is it so difficult to enable this option in superset?

   Also I tried with firefox and geckodriver and facing the same issue. All 
required installation are in correct path variable.
   Either i get the above error or  **devtoolsactiveport file doesn't exist** 
error.
   
   **What am i missing here? What is the correct way to enable email scheduling 
in AWS EC2 instance(Ubuntu)?**
   **Did anybody faced the same issue? If so can someone please help me fix 
this issue**
