Summary

This PR fixes issue #6950 where users were experiencing "Error loading webview: Error: Could not register service worker" when trying to start Roo Code in VSCode.

Problem

The PostHog analytics library was attempting to register a service worker, which is not supported in VSCode webview contexts. This caused the webview to fail to load with an InvalidStateError.

Solution

  • Added configuration options to the PostHog initialization to explicitly disable service worker features
  • Disabled session recording, toolbar metrics, and other features that might attempt service worker registration
  • Used XHR instead of fetch for network requests to avoid service worker dependencies
  • Updated tests to reflect the new PostHog configuration

Testing

  • All existing tests pass
  • The TelemetryClient tests have been updated to verify the new configuration options

Related Issue

Fixes #6950

Type of Change

  • Bug fix (non-breaking change which fixes an issue)
  • New feature (non-breaking change which adds functionality)
  • Breaking change (fix or feature that would cause existing functionality to not work as expected)
  • Documentation update

Important

Disables PostHog service worker features in TelemetryClient.ts to prevent VSCode webview errors and updates tests accordingly.

  • Behavior:
    • Disables PostHog service worker features in TelemetryClient.ts to prevent VSCode webview errors.
    • Uses XHR instead of fetch for network requests in TelemetryClient.ts.
  • Testing:

Reviewing my own code is like debugging in production - technically possible but morally questionable.

Is intentional? We're trying to avoid service worker issues, but keeping persistence enabled might still cause problems in VSCode webviews since localStorage can be restricted. Should this be to fully prevent any persistence-related issues?

The configuration seems redundant - PostHog should handle Content-Type automatically. Is this actually needed to prevent service worker registration, or could we remove it to simplify the config?

Consider grouping these options more clearly or adding more specific comments. For example, isn't obviously related to preventing service worker registration. Maybe separate the options into groups like 'service worker prevention', 'feature disabling', etc?

The test only verifies some of the new configuration options. Should we add assertions for all the new config properties (, , , , , etc.) to ensure they're properly set?

Same issue here - missing test assertions for several of the new configuration options. Consider adding comprehensive checks for all PostHog init parameters to prevent regression.
