Can not deserialize instance of com.atlassian.jira.rest.v2.issue.IssueUpdateBean out of START_ARRAY

Question

I am getting this error when sending a PUT request rest/api/2/issue/issueKey

{"errorMessages":["Can not deserialize instance of com.atlassian.jira.rest.v2.issue.IssueUpdateBean out of START_ARRAY token
 at [Source: org.apache.catalina.connector.CoyoteInputStream@56413a53; line: 1, column: 1]"]}

Request body is: 
{
  "update":{
       "customfield_10802":[
            {
                "set":{
                   "value":"ja"
                }
            }          
         ]
   }   
}

Any Ideas ?

The same payload works correctly when I run the request via Postman. Only when I run the request with code, I get the error message.

I use code. More specifically, I use the Google Ouath client to perform the PUT request.

Something like the following code snippet:

public void updateJiraIssue(String issueKey, String jiraAccesstoken, String verfifier) throws JiraConnectionException {

ObjectMapper mapper = new ObjectMapper();
ObjectNode bodyNode = mapper.createObjectNode();
ObjectNode updateNode = bodyNode.putObject("fields");
bodyNode.putObject("update");
ObjectNode customfield_10802 = mapper.createObjectNode();
customfield_10802.put("value", "ja");
updateNode.set("customfield_10802", customfield_10802);

try {
OAuthParameters parameters = jiraOAuthClient.getParameters(jiraAccesstoken, verfifier, consumerKey, privateKey);
final HttpContent content = new JsonHttpContent(new GsonFactory(), bodyNode);
putRequest(parameters, new GenericUrl(baseUrlIssue + issueKey), content).get();

} catch (Exception e) {
e.printStackTrace();
log.error("Error while handling request to {}", baseUrlIssue, e);
throw new JiraConnectionException("Error handling request when update issue by id.", baseUrlIssue, e);
}

}

How this payload is generated ?

Do you do in in code or do you try using a tool such as Postman ?

Seems like there is a special character somewhere or encoding issue.
