  "type": "https://docs.get-exo.com/errors/job_not_cancelable",
  "title": "Job not cancelable",
  "status": 409,

}
```

## Why it happens

Only a job that has not yet been claimed by a worker can be canceled. Once it is running there is no mid-flight abort, and once it is terminal there is nothing to cancel.

## How to fix it

* Read the job's current `status` with `GET /v1/jobs/{job_id}`. A running job will reach a terminal state on its own.
* Do not poll the cancel route. The answer will not change.
