What version of the IDE extension are you using?

26.422.62136

What subscription do you have?

Pro

Which IDE are you using?

VS Code

What platform is your computer?

Darwin 25.4.0 arm64 arm

What issue are you seeing?

When I select a long-running chat, nothing appears in the Codex sidebar. Sometimes I can get the chat to appear if I click around to another chat and reload it, but not all the time. A loading bar with a percentage or some indication its loading would be very helpful. Otherwise I dont think its doing anything and start clicking around.

What steps can reproduce the bug?

  1. Create a long-running chat in the codex extension
  2. Close VS Code
  3. Open VS Code
  4. Attempt to load the chat

What is the expected behavior?

The expected behavior is the chat loads(at least partially) immediately.

TL;DR

The issue with the Codex sidebar not loading long-running chats in VS Code may be resolved by implementing a loading indicator to provide feedback during the loading process.

Guidance

  • The problem seems to be related to the loading of long-running chats, and providing a loading indicator could help mitigate the issue.
  • To verify if the chat is indeed loading, check the network requests or console logs in VS Code to see if there are any requests being made to load the chat.
  • Consider adding a loading bar or a percentage indicator to the Codex sidebar to provide feedback to the user while the chat is loading.
  • If the issue persists, try to reproduce the bug with a smaller chat to see if the problem is specific to long-running chats.

Example

No code example is provided as the issue does not contain enough technical details to create a specific code snippet.

Notes

The provided information does not contain enough technical details to pinpoint the exact cause of the issue, and the suggested solution is based on the symptoms described.

Recommendation

Apply workaround: Add a loading indicator to the Codex sidebar to provide feedback to the user while the chat is loading, as this may help mitigate the issue and improve the user experience.
