Can't get Custom Attributes to pull into Zapier through webhooks

Hello,
I am seemingly unable to figure out how to get my user responses into a Google sheet.

When in Zapier, I don't ever see any custom attributes available to map.

All custom attributes are available and visible in the "Webhooks attributes" section of the Connections screen.

I have verified the webhook repeatedly. Always OK. I can't tell whether this is on Zapier's side or Snatchbot.

What is needed to get the attributes detected to map, and values to be sent.

I have set up webhooks in all necessary responses, and have been setting custom variables and attributes as needed.
