Stuck on interpreting the correlation between PII redaction processing times and subsequent timeout errors within our Architect flows for the EU-West BYOC environment. The compliance team mandates real-time masking of SSN and credit card numbers using the Data Masking action before routing to external APIs. However, the Performance Dashboard indicates a spike in Flow Execution Time specifically at the masking node, leading to intermittent 504 Gateway Timeout responses from the downstream integration.
The flow configuration is standard, utilizing the built-in masking patterns. Yet, the audit logs show successful masking events, while the operational metrics suggest the processing delay exceeds the configured timeout threshold of 5000ms.
flow_id: "fl_8839201-xc99-4a1b-bc3d-223344556677"
node_type: "data_masking"
patterns:
- name: "SSN"
type: "regex"
value: "^\\d{3}-\\d{2}-\\d{4}$"
- name: "Credit Card"
type: "regex"
value: "^\\d{4}\\s?\\d{4}\\s?\\d{4}\\s?\\d{4}$"
timeout_ms: 5000
Is there a known latency issue with the PII masking service in the EU-West region during peak hours? The business requires strict adherence to GDPR compliance without compromising call flow stability. Any insights into optimizing this configuration or identifying the root cause of the timeout variance would be appreciated.
