# RESOURCE_UNUSABLE

> Resource can't be used (400)

An id in the request names something this endpoint can't read; `errors` names the field and `reason` says why.

| Status | Retryable | Title |
| - | - | - |
| `400` | No | Resource can't be used |

## Common causes

* `api_version_1`: API version 1 created it.
* `older_format`: its result is in a format this endpoint no longer reads.

## What to do

Run the job again with API version 2 and send its new id.

## Example

```json theme={null}
{
  "type": "https://docs.runpulse.com/errors/resource-unusable",
  "title": "Resource can't be used",
  "status": 400,
  "detail": "parse_id: this id was created by API version 1",
  "instance": "urn:pulse:request:req-6f1c2a9e-3b7d-4c55-9a8e-2d4f0b1c7e93",
  "code": "RESOURCE_UNUSABLE",
  "request_id": "req-6f1c2a9e-3b7d-4c55-9a8e-2d4f0b1c7e93",
  "retryable": false,
  "errors": [
    {
      "field": "parse_id",
      "pointer": "#/parse_id",
      "issue": "this id was created by API version 1"
    }
  ],
  "reason": "api_version_1"
}
```
