Context:
POST /api/v2/wfm/schedules/publish returns HTTP 502 Bad Gateway immediately after payload submission. Environment is Genesys Cloud BYOC with local Edge nodes handling WFM traffic. Timezone is America/Chicago. WFM SDK v2.1.0.
Question:
Is the 502 caused by Edge node certificate validation against the WFM service principal, or is there a specific timeout configuration for schedule publishing on private edges?
Have you tried checking the Edge node logs for TLS handshake failures, as this often indicates a certificate mismatch rather than a timeout issue.
Note: WFM schedule publishing is unrelated to recording exports or legal holds.
Check the Edge proxy timeout settings before digging into certs.
proxy_read_timeout to 60s in the Nginx config on the Edge node.502s on large WFM payloads are almost always connection drops due to default 60s timeouts being hit too early.
The way I solve this is by adjusting the proxy timeout, as the suggestion above points out. The 502 Bad Gateway is frequently a symptom of the Edge node dropping the connection before the WFM service finishes processing the schedule publish request, especially for large datasets.

While certificate mismatches can cause connectivity issues, they typically result in immediate 401 or 403 errors, or TLS handshake failures visible in the logs. A 502 specifically indicates that the upstream server (WFM) did not respond in time for the proxy. Increasing proxy_read_timeout to 120s in the Nginx configuration on the Edge node is a standard mitigation. This allows sufficient time for the WFM engine to validate and commit the schedule data. Ensure the Edge service is restarted after modifying the config to apply these changes. This aligns with standard practices for handling large payload submissions in BYOC environments.
