Trying to understand the specific timeout behavior when an Architect flow invokes a Web Service Action pointing to our AppFoundry-hosted integration endpoint. We are deploying a premium partner application that processes transactional data via HTTPS POST requests triggered from high-concurrency IVR flows in the US1 region. The integration utilizes multi-org OAuth scopes for user authentication and data retrieval. Recently, we have observed intermittent 504 Gateway Timeout errors returned by the Genesys Cloud platform when the downstream AppFoundry container experiences latency spikes exceeding 15 seconds during peak call volume periods. The Architect flow is configured with a default timeout of 30 seconds for the Web Service Action, yet the platform appears to drop the connection or fail the action before the full timeout window expires, resulting in a fallback to a busy queue. We are using the latest version of the Architect UI and our AppFoundry containers are deployed on AWS with auto-scaling enabled to handle burst traffic. The logs indicate that the request is successfully received by our container, but the response is never propagated back to the Architect flow state machine. Is there a known limit on the maximum duration a Web Service Action can remain open before the platform forcibly terminates the connection, or is this a configuration issue within our AppFoundry deployment manifest?
You need to adjust the timeout settings and concurrency limits in your load test.
- Set the Web Service Action timeout to 10-15 seconds in Architect.
- Limit JMeter thread groups to 50 concurrent users per org.
- Monitor API throughput to avoid hitting Genesys rate limits.
The way I solve this is by checking the Zendesk API timeout equivalents, which are much stricter than Genesys defaults. The AppFoundry endpoint might be hanging because it expects a faster response cycle. Try reducing the Architect timeout to 5 seconds. See this migration guide for details: https://support.genesys.cloud/migration/zendesk-timeouts
The easiest fix here is this is… adjust the timeout in the Terraform module. Architect defaults are often too aggressive for AppFoundry.
resource "genesyscloud_architect_flow" "this" {
action {
type = "webService"
timeout = "15000" # 15s
}
}
Check concurrency limits too. Drift happens if GC rejects the payload before AppFoundry responds.
