Calling POST /api/v2/flows/executions from our Kotlin backend to kick off a specific Architect flow. The endpoint returns 202 Accepted immediately, which is expected, but the flow execution never shows up in the monitoring UI. The JSON payload includes the correct flowId and languageCode. I’ve verified the x-gc-accepted-language header is set. Any idea why the async job might be silently failing or dropped?
check the x-gc-request-id header in the 202 response and pass it to GET /api/v2/asyncjobs/{asyncJobId}. the job is probably failing validation on the payload structure, and the error details are hidden in the async job status.
