204 - Change Number In Use¶

API Error Code	204
HTTP Status Code	HTTP 409 Conflict
Error Text	`The change number specified has already been used`
Description	The change number used to create a new review request wasn’t valid, because another review request already exists with that change number. You will only see this with repositories that support server-side changesets, such as Perforce. Usually, the correct thing to do is to instead modify the other review request. The resource information for the review request that’s associated with the change number will be returned in the `review_request` key.

Example¶

{
  stat: "fail",
  err: {
    code: 204,
    msg: "The change number specified has already been used"
  },
  review_request: {
     ...
  }
}
