Closes elastic#254222 ## Summary This PR fixes uncaught errors when APM data has missing `service` or `service.environment` (e.g. OpenTelemetry or incomplete documents). The UI was reading `error.service.environment`, `transaction.service.environment`, and similar properties without optional chaining, causing "Cannot read properties of undefined (reading 'environment')" and error boundary crashes. This PR: - Adds optional chaining and fallbacks to `ENVIRONMENT_NOT_DEFINED` / `getEnvironmentLabel` where service or environment may be missing - Updates **error group details**: error sample detail, contextual insight, and sample summary (optional `error`/`service`, safe access to `error.error`) - Updates **transaction/span flyouts**: transaction flyout, view full trace link, span flyout sticky properties - Updates **agent configuration link**: safe access to `configService?.name` and `configService?.environment` ## How to test - Use APM with data that has no `service` or no `service.environment` (e.g. OTel or incomplete documents): If using synthtrace I added a scenario: - Run `node scripts/synthtrace missing_service_environment --from=now-1h --to=now+1h` - Confirm that the service.environment is not in the document and there is no error in the flyout: <img width="3446" height="1962" alt="image" src="https://github.com/user-attachments/assets/04867ef0-f89b-4601-b0bf-381a795ab2a6" /> - Open error group details and an error sample, transaction flyout, span flyout, or a view that uses agent config service - Confirm the UI no longer crashes and shows "Not defined" (or equivalent) for missing environment where appropriate: <img width="3456" height="1994" alt="image" src="https://github.com/user-attachments/assets/21fb7684-2c40-4eb5-b83d-063d9b2437be" /> https://github.com/user-attachments/assets/19c46cb3-ff2e-4938-8cf3-2316f7a1a4ae --------- Co-authored-by: kibanamachine <42973632+kibanamachine@users.noreply.github.com> (cherry picked from commit f0e605f) # Conflicts: # x-pack/solutions/observability/plugins/apm/public/components/app/error_group_details/error_sampler/error_sample_detail.tsx
