Predictive Routing API 502 on Trunk Failover Toggle

What is the reason the Predictive Routing API returns 502 Bad Gateway when toggling failover priority for our 15 BYOC trunks in apac-1? Using SDK 2.4.1, the request hangs until timeout despite valid SIP credentials and correct outbound routing rules. No issues with direct outbound calls, only during routing config updates.

The easiest fix here is this is…

  • check if genesyscloud_routing_emergency_group dependencies are locked in state
  • retry with genesyscloud_api timeout set to 60s in provider config

It depends, but generally… 502s during config updates often stem from backend service overload rather than SIP issues. Since I’m focused on API throughput, this might be a rate-limiting side effect masquerading as a gateway error. Check these:

  • API response headers for Retry-After
  • Concurrent write requests to the same resource
  • Region-specific backend latency spikes
