# chat_provider_request_invalid

> The platform sent a malformed request to the upstream model.

**Code**: `chat_provider_request_invalid`
**HTTP status**: `500`
**Type**: `server_error`

## When it fires

The upstream model rejected the request as malformed. This is **a platform-side bug** — your input passed our DTO validation but the shape we forwarded didn't satisfy the upstream. Logged at ERROR so engineering gets paged. Any held credits are released.

## How to recover

Retry with backoff — the bug is being investigated. Open a support ticket with the response `request_id` so we can correlate to the exact log line.
