I have been trying to integrate WhatsApp notifications using Twilio. I have been following the steps as per this video Understanding How to Integrate Twilio with ERPNext - YouTube. Whenever I try to open Twilio Settings from the integration page, it shows an error “DocType Communication Medium not found” & “The resource you are looking for is not available”.
I have installed the twilio integration and have setup a notification alert on submission of Sales order. But the notification does not succeed and it shows this error.
Traceback (most recent call last):
File "/home/aaron/frappe-bench/apps/frappe/frappe/email/doctype/notification/notification.py", line 137, in send
self.create_system_notification(doc, context)
File "/home/aaron/frappe-bench/apps/frappe/frappe/email/doctype/notification/notification.py", line 168, in create_system_notification
if "{" in subject:
TypeError: argument of type 'NoneType' is not iterable
Am not sure what does this error mean and how to correct it.
Please help!!!
