# Cancelled

## What it means

The run was cancelled before it finished, so nothing more of it runs. Anything it did before then, such as calling a tool, may already have taken effect.

## What to do

Read the problem's `detail` first. It says what happened to this request.

*   The `kind` says why: someone asked (`requested`), the workflow waiting for it ran out of time (`deadline`), it ran as long as a workflow may run (`overrun`), or the workflow waiting for it ended first (`parent_ended`).
*   Check the run's history with `get_run_history` to see what it did before it stopped.
*   If the work is still needed, start a new run with a new `run_id`. The same `run_id` returns this cancellation again.

## Technical details

*   Type: `https://on.auto/problems/cancelled`
*   Status: 409
*   Reason: `cancelled`
*   `kind`: why the run was cancelled: `requested`, `deadline`, `overrun` or `parent_ended`
