🐛 Destination BigQuery-Denormalized: cannot format root of NULL with nested objects

[bazarnov]

Current Behavior

• During the sync, the connector outputs the complex data structure with a lot of nested objects/arrays with objects/ etc.
• If the root node == null and the json schema of the stream contains nested objects as expected by the destination, but data is not present - the destination fails with the error. (see the logs attached).

Expected Behavior

• Sync finished successfully

Possible solution

In theory we should check for the root object is not empty first, if so - drill down formatting nested data, otherwise - set the null.

Logs

Steps to Reproduce

1. Setup the source-shopify from this PR
2. Setup destination-bigquery-denormalized, using the latest version.
3. Run the sync using one of: draft_orders, products streams.

Also, adding the sample of the expected data from draft_orders stream.

The root cause of this issue is not about root of NULL containing nested object itself it's about containing nested date-time field
