Stuck on a 504 Gateway Timeout when hitting a custom Data Action in Architect under load. Running JMeter with 500 threads against the POST /api/v2/integrations/dataactions endpoint.
The flow hangs and returns 504 after 60 seconds, but single-threaded requests succeed instantly. Environment is AP-Southeast-1. Using SDK v2.20.400.
Is there a hidden rate limit for Data Action invocations per org? The standard API limits don’t seem to apply here.
