New Files Created:

Technical notes summary

Architecture:

• Uses Vue 3 Composition API with TypeScript
• Follows existing Epinio codebase patterns and conventions
• Leverages existing utilities (downloadFile from @shell/utils/download)
• Uses Vuex store for API requests via epinio/request action

Error Handling:

• Custom SupportBundleError class with error codes for translation support
• Comprehensive error mapping:
  • 401 - Authentication required
  • 403 - Admin access required
  • 400 - Invalid parameters
  • 500 - Server error
  • Network errors and timeouts
  • Download failures
• All error messages are internationalized

Areas or cases that should be tested

Functional Testing:

1. Basic Download Flow:
   • Navigate to Support Bundle page (sidebar → System → Support Bundle, or URL: /epinio/c/<cluster>/support-bundle)
   • Click "Download Support Bundle" with default options
   • Verify file downloads with correct filename format
   • Verify file is a valid tar.gz archive

Areas which could experience regressions
