Stuck on a timeout issue with an external data action in GC architect. the action is a simple POST to an internal python service that caches responses in redis. the service responds in 4-5 seconds consistently because it’s doing a heavy lookup + cache miss penalty. architect data actions seem to hard-limit to 3 seconds. i get a 504 gateway timeout from the platform side before my service even finishes.
is there a way to increase this limit via the data action config? i’ve tried setting timeout_ms in the json config but it doesn’t seem to apply. here is the config i’m using:
the sdk call works fine directly. but in architect flow it fails. is this a hard platform limit? or am i missing a parameter? i need to handle these slower lookups without failing the interaction.
I’d recommend looking at at the HTTP response headers and the actual payload structure returned by your FastAPI endpoint. The documentation states: “The external service must respond within the timeout period. For data actions, this is typically 3 seconds.” If you are hitting a 504, the platform is terminating the connection because it expects a specific JSON schema or the handshake is failing, not just because of the raw network latency.
My Python backend often hits this when the Content-Type header is missing or when the response body does not match the expected application/json format strictly. Ensure your FastAPI endpoint returns Response(status_code=200, content=json.dumps(result), media_type='application/json'). Also, check if you are using client_credentials flow. If the token expires during that 4-5 second window, the request fails before the data action even processes it.
Here is a minimal FastAPI snippet that works reliably with GC Data Actions:
from fastapi import FastAPI
import json
app = FastAPI()
@app.post("/genesys-data-action")
async def handle_gc_request():
# Simulate heavy lookup
result = {"key": "value", "cached": True}
# Explicitly return JSON with correct headers
return {"status": "success", "data": result}
If you need more than 3 seconds, you cannot change the Data Action timeout. You must switch to a Call Control or Webhook pattern. Push the data asynchronously. The documentation notes: “For long-running processes, use webhooks to notify Genesys Cloud upon completion.” Do not block the Architect flow.
Verify Content-Type: application/json headers
Check OAuth token validity during the request window

Consider asynchronous webhook patterns for long processes
the problem here is assuming architect data actions can handle synchronous long-running processes. the 3-second limit is hard-coded for ui responsiveness and cannot be increased via config. your python service returning in 4-5 seconds will always trigger a 504 gateway timeout from the platform gateway, regardless of redis caching strategies.
you need to decouple the flow from the heavy lookup. use architect’s “queue message” or “send email” actions to trigger an asynchronous job, or expose a lightweight endpoint that returns a job id immediately. your go client can then poll a separate status endpoint using exponential backoff. here is a minimal polling helper using purecloudlabs/go-platform-client to check job status without blocking the architect flow:
func pollStatus(client *platformclientv2.PlatformClient, jobId string) error {
for i := 0; i < 5; i++ {
time.Sleep(time.Duration(math.Pow(2, float64(i))) * time.Second)
resp, _, err := client.ApiClient.Get(jobId)
if err != nil { return err }
if resp.Status == "completed" { return nil }
}
return fmt.Errorf("job timed out")
}
