Predictive Routing assignment delay with ServiceNow webhook dependency

Just noticed that predictive routing assignments are stalling when the Data Action invoking the ServiceNow REST API takes longer than 500ms. The call flow is configured to wait for the ticket creation status before proceeding to the queue, but the predictive engine seems to timeout or drop the prediction score if the external call isn’t immediate. Is there a specific timeout threshold for external API calls within predictive routing logic that I am missing?
