Looking for advice on handling script step timeouts within the Architect flow. The flow hangs at the script execution node when processing high-volume inbound calls, specifically returning a 504 Gateway Timeout after 12 seconds. The payload structure remains constant across all attempts.
{
"scriptId": "849201-4455-6677-8899-001122334455",
"stepId": "main_inquiry",
"context": {
"callerId": "+33123456789",
"queueId": "paris_support_main"
}
}
Is this a known limitation of the Paris edge region, or should the timeout threshold be adjusted in the flow configuration?
It depends, but generally…
The 504 Gateway Timeout in the Paris edge environment is rarely a pure latency issue when the payload is static. It is usually a configuration mismatch in the script execution limits or a deadlock in the dependency chain within the Architect flow. Since the payload structure is constant, the script itself is likely executing, but the timeout threshold for the specific step is being hit before the response is returned to the flow.
Check the genesyscloud_script configuration in your Terraform state. The default timeout for script steps is often lower than expected in high-load environments. You need to explicitly set the timeout value in the script definition.
resource "genesyscloud_script" "main_inquiry" {
name = "Main Inquiry Handler"
description = "Handles inbound inquiries for Paris edge"
flow_steps {
id = "main_inquiry"
type = "script"
script_config {
script_id = "849201-4455-6677-8899-001122334455"
timeout = 30 # Increase from default if applicable
}
}
}
Additionally, verify the genesyscloud_routing_queue settings for paris_support_main. If the queue has aggressive service level objectives (SLOs) or long queue wait times, the script execution might be competing for resources with other flow steps. Ensure that the script does not contain any synchronous HTTP calls to external endpoints that are experiencing high latency.
If the script makes outbound API calls, consider using async patterns or increasing the timeout in the script code itself. The GC CLI can help debug this by showing the actual execution logs:
genesyscloud scripting:script:logs --script-id 849201-4455-6677-8899-001122334455 --last 10
Warning: Increasing timeouts blindly can mask underlying performance issues in the script logic. Always profile the script execution time first.
Pretty sure the Paris edge environment has stricter latency tolerances for outbound HTTP calls compared to the US or EU-West nodes. When managing multiple BYOC trunks, I’ve seen this exact 504 pattern when the script step tries to reach a backend service that isn’t whitelisted in the regional firewall rules.
{
"timeoutMs": 8000,
"retryPolicy": {
"maxRetries": 2,
"backoffMs": 500
}
}
The default timeout is often too aggressive for cross-region calls. Try reducing the script step timeout to 8 seconds and adding a simple retry policy. This prevents the flow from hanging while waiting for a connection that might be blocked. Also, verify that the destination URL is accessible from the Paris edge IP ranges. If the payload is static, the issue is almost certainly network-related rather than a logic error in the script itself. Check the network logs for any dropped packets between the edge and your backend service.
Pretty sure the 504 error during high concurrency is often a connection pool exhaustion issue rather than just latency. Check if your backend supports enough simultaneous WebSocket connections for the load spike. The Paris edge might be dropping idle connections faster, causing the script step to fail when retrying.
