Research direction

Start by reproducing the failure with extension version openai.chatgpt-26.715.31925 in VS Code and inspect the ChatGPT/Codex Webview Developer Tools. Examine the generated Vite entry point and its approximately 676 JavaScript and CSS preloads. Done means the Webview initializes reliably without preload, service-worker, or net::ERR_FAILED errors.

What issue are you seeing?

The Webview may fail to initialize and show one or more of the following symptoms:

  • The loading animation never completes
  • Blank or gray Webview
  • JavaScript or CSS preload failures
  • Service Worker registration failure
  • Local Webview resources fail with net::ERR_FAILED

The developer console may also contain errors or warnings similar to:

potential listener LEAK

Service Worker registration failed because the document state became invalid
What steps can reproduce the bug?

  2. Open the ChatGPT/Codex Webview from the VS Code sidebar.
  3. Open the Webview developer tools:
    • Run Developer: Open Webview Developer Tools from the Command Palette.
    • Select the ChatGPT/Codex Webview if prompted.
  4. Reload the Webview or restart VS Code.
  5. Observe that the generated Vite entry point attempts to preload approximately 676 JavaScript and CSS resources at once.
  6. In affected environments, the Webview remains on the loading animation or becomes blank or gray.
What is the expected behavior?
