# E01000 — InternalError

An internal error occurred.

- **HTTP status**: `500`
- **Type**: `internal_error`
- **Name**: `InternalError`

## What to do

Something failed on Bird's side while processing the request. Retry with exponential backoff, reusing the same `Idempotency-Key` so the retry is safe. If it persists, contact support and quote the response's `request_id`.
