Accessing navigator.userAgent without a guard can crash in non‑browser contexts. Consider guarding with typeof navigator !== 'undefined' (like in Context) before setting the tag.

Suggested change
diagnosticsClient.setTag('user_agent', navigator.userAgent);
if (typeof navigator !== 'undefined') {
diagnosticsClient.setTag('user_agent', navigator.userAgent);
}
