# FILE_URL_INVALID

> Invalid file URL (400)

`file_url` isn't a link Pulse may fetch.

| Status | Retryable | Title |
| - | - | - |
| `400` | No | Invalid file URL |

## Common causes

* The link isn't `http`, `https`, `s3` or `gs`.
* The link points at a private network address.
* On Pulse's hosted API, the link points into Pulse's own storage unsigned.

## What to do

Send a public or presigned link to the file.

## Example

```json theme={null}
{
  "type": "https://docs.runpulse.com/errors/file-url-invalid",
  "title": "Invalid file URL",
  "status": 400,
  "instance": "urn:pulse:request:req-6f1c2a9e-3b7d-4c55-9a8e-2d4f0b1c7e93",
  "code": "FILE_URL_INVALID",
  "request_id": "req-6f1c2a9e-3b7d-4c55-9a8e-2d4f0b1c7e93",
  "retryable": false
}
```

In API version 1 this was `FILE_007`.
