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.

In your linked service connection settings, have you tried the additional connection properties to support the v1 data types?
Now I have tried it and it works!! Thank you
