Cannot transition an issue using Rest API

Question

I am using an on premises edition of Jira server V8.15.0 and writing code in C#

The issue is already created so I used an API call to get the metadata and thus the id for the issue.

I then used: "/baseUrl/api/2/project/projectKey/statuses" to get all the statuses for the project and thus the status id corresponding to the status I want to transition the issue to.

I then created a response body:

"{\"transition\": {\"id\": \"" + statusId +"\"}}"

-or-

{"transition": {"id": "statusId"}}

I then POST the request to:

"/baseUrl/api/2/issue/issueId/transitions";

however this generates a 500 code "Internal Server Error"

Any  idea what I could be doing wrong?

Thanks,

Ken O'Brien

I have checked the application log file (atlassian-jira.log, actually the server guy just sent me a copy of it) at about the time the internal error is generated.  I see nothing suspicious.  No mention of an error.  No mention of transition.  No mention of status.  However, whenever I try to perform a transition it throws it back at me with "Internal Server Error".  Maybe I just don't know what to look for.  It is possible to transition an issue on Jira server through the API correct?

Hi @Ken O_Brien

Have you checked the application logs? atlassian-jira.log file will lead you to this problem as the devil is in the details.
