BASE64 Image From WebHook

Using an endpoint URL for a Webhook post out of the forms provider, I've mapped the relevant fields and receive a 200 for incoming JSON blobs.

The base64 image is not inserting an image into the table and I'm not sure what direction to go next. The resulting webhook post leaves the image field empty.

I've tried variations of the input: json dot notation -
image: base64Upload = input: json request.data.base64Upload.url.data
request.data.base64Upload.url
request.data.base64Upload

The entire submission can be seen here - https://webhook.site/#!/332f1647-583c-4b13-9a9b-cf4b2fd5d9cd/af44cfcb-fdf3-4dc2-8450-7d992b64daf3/1
