Unable to change issue status with REST API

[Than Than Aye]

Hi,

I tried to update an issue transition and comment with the following POST call, but I kept getting errors. It seems that the issue lies in "transition" but I am not sure how to solve this. I could make GET requests and other POST requests like adding comments fine.

url = '/rest/api/2/issue/{issueIdOrKey}/transitions'
payload = {
"update": {
"comment": [
{
"add": {
"body": "test"
}
}
]
},
"transition": {
"id": "2"
}
}
response = requests.post(url,data=payload, headers=headers)

Error Msg

{"errorMessages":["Unrecognized token 'transition': was expecting 'null', 'true', 'false' or NaN\n at [Source: org.apache.catalina.connector.CoyoteInputStream@558dc7a5; line: 1, column: 12]"]}

If I add json.dumps() to the payload, the error messages changes.

{"errorMessages":["Internal server error"],"errors":{}}

 Appreciate your help

have you tried transitioning a different issue or using a different, less restrictive transition to test?  have you tried without the comment?  Start there if you havent yet to help narrow down what may be the issue.

[Randy]

what language are you using?  Python?  

That error indicates your payload is not formatted correctly.

Hi Randy,

Yes, I am using Python.

There was no error when I tested the payload format with some online JSON viewers, and both parameters - 'update' and 'transition' - are also valid, yet I still couldn't update the issue status. What could possibly be wrong here?

use json.dumps .  Checkout the example for python in the docs https://developer.atlassian.com/cloud/jira/platform/rest/v3/#api-rest-api-3-issue-issueIdOrKey-transitions-post

Hi, I did try using json.dumps, and I got this "Internal server error".

{"errorMessages":["Internal server error"],"errors":{}}

[Randy]

post your code

[Than Than Aye]

I only added json.dumps() to the payload. Here is the code

url = '/rest/api/2/issue/{issueIdOrKey}/transitions'
payload = json.dumps({
"update": {
"comment": [
{
"add": {
"body": "Bug has been fixed."
}
}
]
},
"transition": {
"id": transitionID
}
})
response = requests.post(url,data=payload, headers=headers)

[Randy]

Are you able to hit the REST API for anything else successfully or is transitioning the first thing you've done so far with the api?

[Than Than Aye]

I have used the JIRA API for other purpose - getting attachments, adding comments, etc. They are all working fine, except for this updating transitions.

HI,   Have you solved this problem?   I have the  same error  which confuses me whole day,  ahhhhhh

Hi !

I had this error because I was writing a wrong id : the status id instead of the transaction id. To get a valid transaction id, do a get request before ;)

The error message is not very informative due to a bug : https://jira.atlassian.com/browse/JRASERVER-32132.
