action_failed

HTTP 500   title: Action failed

What it means

An operator-registered action raised while running. The wire caught it and rendered a problem document rather than leaking a stack trace — the failure is inside the operator’s own code, on the operator’s side of the seam.

What to do next

Not a client error: the request was accepted and understood. detail carries what the operator chose to say. Retrying an action that raised may or may not succeed — if the action is one that spends money or creates records, verify the resulting state through the operator’s own queries before retrying.

On the wire

This page documents the RFC 9457 type URI https://kiosk.tech/problems/action_failed. The URI is an identifier, not a locator a client should fetch: branch on the document’s code member. The normative definition lives in the error vocabulary of the Kiosk specification (§9 of the formal spec).
