rollup.emitException

Signals that the current request could not be processed — a structural failure, not a business-rule rejection. The exception payload is surfaced to the outside world; the machine treats the request as failed.

Prefer the gentler paths first: return false from a run handler to reject an input, or throw (which run converts to a report plus rejection). emitException is the last resort for "this application cannot meaningfully continue with this request".

Usage

rollup.emitException(Buffer.from("unrecoverable: state corrupted"));

Returns

void
