After the upgrade, an existing mapping fails when all of the following conditions
apply:
The
Google BigQuery V2
connection uses the simple connection mode.
The
Use EXPORT DATA statement to stage
property is enabled in
the source advanced properties.
The transformation includes fields with the Record or Repeat data type from the
source table.
To resolve this issue, remove the fields with the Record or Repeat data type from
the transformation, and re-run the mapping.
After the upgrade, an existing mapping in SQL ELT mode fails if it uses the
REGEXP_EXTRACT function in an Expression or Aggregator transformation with the Byte data
type in the argument and the String data type in the return type.
To resolve this issue,
update the data types in the argument and return type of the REGEXP_EXTRACT function to
compatible formats, and re-run the mapping.
