I am having trouble editing the issue status name

Question

def issueKey = 'QAMEW-14'

def logTest=get('/rest/api/2/issue/' + issueKey)
.header('Content-Type', 'application/json')
.asObject(Map)

logger.info("test ======>>>>> "+logTest.body.fields.status.name)

def result = put('/rest/api/2/issue/' + issueKey)
.header('Content-Type', 'application/json')
.body([
fields:[
status:[ name:"Backlog"
]
]
]
)
.asString()

if (result.status == 204) {
return 'Success'
} else {
return "${result.status}: ${result.body}"
}

I keep getting this error...why:

PUT request to /rest/api/2/issue/QAMEW-14 returned an error code: status: 400 - Bad Request
body: {"errorMessages":[],"errors":{"status":"Field 'status' cannot be set. It is not on the appropriate screen, or unknown."}}

Please use the ScriptRunner user to complete this task not the Initiating User.
See https://docs.atlassian.com/jira/REST/cloud/#api/2/issue-editIssue for more information.
If you are using the ScriptRunner user then check the Field Configuration

Sorry for the late response, that call looks right, I'm assuming that transition 91 is the status change you want to make?

I can't see what the API return in your above response, would you mind posting it?

@Sam Nadarajan it does kind of make sense to me. I guessing it is just my api call? My apologies, I am not that great at coding.

def result = post('/rest/api/2/issue/'+issueKey+'/transitions')
.header('Content-Type', 'application/json')

.body([transition: [id: 91]]

)
.asString()

To replace my put call above?

This is what the api returns I see

Got it.

You actually cannot change the status field directly like you can with other custom fields. To do that you would need to use the HttpRequest for transition issue (that I linked above) instead of the edit issue.

Here's a similar thread that you should also reference.

Hope this helps!
