> In {{FileSinkOperator}}, a serializer is created to write output data. When initializing
it we should not read the {{ColumnProjectionUtils.READ_NESTED_COLUMN_PATH_CONF_STR}} property
since this is only used for the read path, and the path may not match the schema for the output
table (for instance, in the case of insert).
