Failed Rest-Using API to Update Resolution

Michaiah_Gartner

Every time I try to use this code to change a resolution on a ticket:

 

{  "update": {
        "transition": {"id": "45"},
        "fields": {
            "resolution": {"name": "Done"}
        }
    }

 

I get this response:

 

{"errorMessages":["Can not deserialize instance of java.util.ArrayList out of START_OBJECT token\n at [Source: org.apache.catalina.connector.CoyoteInputStream@61704a22; line: 2, column: 9] (through reference chain: com.atlassian.jira.rest.v2.issue.IssueUpdateBean[\"update\"])"]}

 

What does this mean and how can I fix this issue?

Which specific rest endpoint are you calling when you get this error?  If you're calling the POST api/2/issue/{issueIdOrKey}/transitions endpoint as I suspect, you should have the 'transition' and 'fields' parameters on the same level as 'update', and not nested within the 'update' tag itself.

Another user had the same problem in the thread  https://community.atlassian.com/t5/Jira-questions/Unable-to-use-JiraRestClient-or-rest-api-to-transition-issues/qaq-p/257066  Props to @Penny Wyatt (On Leave to July 2021) for the stellar answer there.

I hope this helps.
