[jira] [Created] (FLINK-21266) The POST request caused a JSON serialization error

chenkaiyin created FLINK-21266:
----------------------------------

             Summary: The POST request caused a JSON serialization error
                 Key: FLINK-21266
                 URL: https://issues.apache.org/jira/browse/FLINK-21266
             Project: Flink
          Issue Type: Bug
          Components: Runtime / REST
    Affects Versions: 1.11.3
            Reporter: chenkaiyin


The annotation in the document can request the interface directly, but it will return an error directly。

Post /jobs/:job/savepoints
Post /jobs/:job/stop

An error is reported when serializing "{}" in code：

MAPPER.readValue("{}", untypedResponseMessageHeaders.getRequestClass());

（AbstractHandle.java: 150）

The reason is no configuration @Nullable SavepointTriggerRequestBody.class file cancelJob field
