# Internal error

> internal_error: HTTP 500, retryable.

| | |
| - | - |
| Code | `internal_error` |
| HTTP status | `500` |
| Retryable | Yes |
| Python | `vaquill.InternalServerError` |
| TypeScript | `InternalServerError` |

## What it means

The API failed in a way it did not anticipate.
The call is refunded.

## What to do

Retry with exponential backoff.
If it persists, [contact support](mailto:contact@vaquill.ai) and include the `requestId`.
The SDKs retry this code automatically.

## Example response

The `detail` text is illustrative and can differ by endpoint.
`retryAfterSeconds` appears only on a `429` or `503` that carries a `Retry-After` header.

```json theme={"theme":"github-light"}
{
  "type": "https://www.vaquill.ai/docs/errors/internal_error",
  "title": "Internal error",
  "status": 500,
  "detail": "Internal server error",
  "code": "internal_error",
  "retryable": true,
  "requestId": "3f2b8c1e-5a7d-4e9b-9c34-0d6a1b2f7e58"
}
```

## In the SDKs

The Python SDK raises `InternalServerError` and the TypeScript SDK raises `InternalServerError`.
Both expose `code`, `retryable`, the request id and the retry hint.
See [Error codes](https://vaquill.ai/docs/errors/index.md) for the full table and attribute names.
