3317170 - SSR Coding Common Recommendations

Symptom

An increase in failure rate is being observed, along with degradation in response time. The Server-Side Rendering (SSR) process appears to become stuck, failing to provide a response to Nginx, which leads to a significant number of 504 or 502 exceptions. Additionally, certain logs in the jsapps-ssr container display errors such as:

  • ERROR ReferenceError: sessionStorage is not defined 
  • ERROR ReferenceError: window is not defined 
  • ERROR ReferenceError: document is not defined 
  • ERROR ReferenceError: self is not defined
