# internal_error

**HTTP status:** 500 (Server error)

**Title:** Internal error

## Cause

Something failed on our side after the request started. The same Idempotency-Key returns this same error, so check whether the operation happened before retrying with a new key.

## How to fix it

Check whether the operation happened, then retry with backoff and a new Idempotency-Key: the same key returns this error again. If it keeps failing, report the requestId.

Send the same request again.

Parameter: `Idempotency-Key`

Every error carries `requestId` and the `Request-Id` header. Send it when you write to support.
