Error in copy activity with Oracel 2.0

I need to add to this that the solution to my situation was to add the following line to the Parquet dataset json code:

"useParquetV2": true

at the same level as compressionCodec

in combination with adaardor suggestion with "Support V1 data types" above. Without it the Parquet file could not be read by Databricks with the error that decimal precision of 256 is not allowed, max 38.

Full code for Parquet dataset:
