Description
When the java class has been generated using one of the Temporal logical types and then converted to JSON using toString(), the output field does is not a proper string:
"operationTime": 2021-04-29T04:01:57.465Z
This is an ISO-8601 compliant string, so it should be treated as a string:
"operationTime": "2021-04-29T04:01:57.465Z"
