Steps taken:

  1. On Power BI Desktop, click File > Options and settings > Options.
  2. Click Preview Feature.
  3. Select Use new Databricks connector implementations.
  4. Reboot 
  5. Manual run query in m query using Implementation = 2.0 (which has been the use case for these scripts

While the m query can run without Implementation = 2.0, doing that causes material problems since the Big Query JSON needs 2.0 to parse correctly
