Looks good so far. Continue to the next step in the guide.
You must set
formRequest = THE_ENTIRE_API_RESPONSE as JSON, not as a string.
This is not a well-formed
You can get a
form_request using the "Create form request" action of the API or in the API's interactive documentation.
It looks like you copied the docs' example
form_request response. Create your own
form_request and use that instead.
