Request failed validation

[rdeshmukh15]

Several of our customers are experiencing the following intermittent issue while running the adCreatives API. We are using facebook-ads version v21.0 and facebook_business version 21.0.5.

Tap failed with code -15. Target failed with code 1 and error message: "Error persisting data to Stitch: 400: {'error': 'Request failed validation:\n#/messages/689: #: 0 subschemas matched instead of one\n#/messages/689: 2 schema violations found\n#/messages/689: extraneous key [data] is not permitted\n#/messages/689: extraneous key [time_extracted] is not permitted\n#/messages/689/data: expected type: JSONObject, found: Null\n'}".

Here’s the codebase we're working with: https://github.com/singer-io/tap-facebook

Since the release of these changes: tap-facebook PR #242, we've been encountering this error intermittently.

I attempted to add the data and time_extracted fields to the schema in adcreative.json, but that didn't resolve the issue.

The error mentioned above seems to be originating from this line of code: target-stitch/init.py#L809.

Can you guide us why we are getting these errors?
