I can’t seem to figure out why the Data Action integration fails with a 504 Gateway Timeout when triggered from the Architect flow. The external endpoint responds correctly via Postman, yet the flow logs indicate a connection reset after 30 seconds.
- Verified the Data Action payload structure matches the REST API documentation exactly.
- Increased the timeout threshold in the flow configuration to 60 seconds without resolution.
Is there a known limitation for HTTP POST requests within the EU-Paris region?
Ah, this is a recognized issue…
The 504 timeout often stems from the external service not responding within Genesys Cloud’s internal keep-alive window, even if the flow timeout is set higher. The connection drops before the payload is fully processed.
Check your server logs for this specific reset indicator:
Connection reset by peer: HTTP/1.1 504 Gateway Timeout
A common fix is to adjust the JMeter configuration to simulate the exact header structure Genesys Cloud sends. Ensure Transfer-Encoding: chunked is handled correctly by your backend.
In your load test, add this header to prevent early termination:
Connection: keep-alive
Content-Length: [exact_size]
Also, verify the API rate limits. If the endpoint throttles during peak load, the 30-second mark is when the buffer overflows. Try adding a small delay in the JMeter thread group to see if the stability improves. This usually points to backend processing latency rather than a Genesys configuration error.
