I am using python to create webhook for Assistat app. I am able to ask user for location permission, but as soon as user gives consent, I receive following error
UnparseableJsonResponse
API Version 2: Failed to parse JSON response string with 'INVALID_ARGUMENT' error: ": Cannot find field.".
I have checked my webhook server and no request comes to it. This looks like some issue at API.ai side.
Below is the Debug response from Actions console when using Python client

Using Python library Flask-Assistant
How can I resolve this issue?
UPDATE
Node JS client works... what is the issue with Python client?

API.ai Intent settings
The most likely reason you're not getting any hits on your webhook is that you don't have an intent registered to get the reply.
You can do this by creating an Intent with the Event set to
actions_intent_PERMISSION.See also the following answers on SO:
