engine_refused

Runtime refused the call · HTTP 502

What causes this

Our integration runtime refused the call before it reached the provider — for example a configuration it does not accept. The provider was never asked. This is our side, not yours.

How to fix it

Retry — this class is transient, and a flow keeps retrying on its own. Quote the request_id if it persists.

Quote the request_id if you contact support — it identifies your exact request in our logs.
