So it seems there is a BUG in the Pipeline that is causing me all this grief. The WORKAROUND is the following:
Can anyone translate this to CSV from Parquet. I have tried various permutations for CSV but no success yet (not sure if this will ever work).
BTW - there is supposed to be a bug fix for this in a 7.8.* release soon. This is the second huge roadblock by SIngleStore in me getting my data loaded. Hopefully this is not a pattern. The other issue was running a Pipeline on the Azure GOV cloud (not supported).
