Stuck on Architect IVR Data Action timeout to ServiceNow

Context: Architect flow triggers a Data Action to ServiceNow via webhook. The endpoint responds in 1.2s, but GC logs show a 504 Gateway Timeout after 30s. Network traces confirm the payload leaves the MID server correctly.

Question: Is there a hidden retry logic or timeout override in the Data Action connector that forces this failure, or should I be looking at the Architect flow timeout settings?
