# conflict

The `conflict` error occurs when a request cannot be completed because the resource is in a state that conflicts with the requested operation.

***

## Details

* **HTTP Status:** `409 Conflict`
* **Retryable:** Yes
* **Task State:** FAILED

***

## When does this occur?

This error is returned when:

* You attempt to cancel a task that is still in the **pending** state (the task has not yet been claimed by a worker)

The operation can typically succeed once the resource transitions to the expected state.

***

## Example response

```json
{
  "type": "https://docs.warp.dev/reference/api-and-sdk/troubleshooting/errors/conflict",
  "title": "Pending agent runs cannot be cancelled, retry after a moment.",
  "status": 409,
  "instance": "/api/v1/agent/tasks/abc123/cancel",
  "error": "Pending agent runs cannot be cancelled, retry after a moment.",
  "retryable": true
}
```

***

## How to resolve

1. Wait a moment for the resource to transition to the expected state.
2. Retry the request.

For task cancellation specifically, wait until the task moves from **pending** to **in progress** before attempting to cancel.
