Cursor IDE

Describe the Bug

On cursor version 2.5.17, any chat prompt with an @.file reference causes the chat to get stuck in “Planning next move” indefinitely.

Steps to Reproduce

  • Fresh install of Cursor 2.5.17
  • Create an empty folder with a single text file containing some text
  • Open folder in Cursor and send any chat prompt containing an @.file reference to the file
  • Chat hangs indefinitely on planning next move

Expected Behavior

  • Chat should not hang when prompt includes @.file reference

Operating System

MacOS

Additional Information

Downgrading to Cursor 2.4.37 resolved the issue.

Attempted solutions that did not work:

  • tried disabling HTTP 2.0
  • tried clearing Cursor application caches
  • tried a full re-install of Cursor 2.5.17
  • tried deleting/re-building code index

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, thanks for the report. I couldn’t reproduce this on my side, so it might be something specific to your environment.

Can you share a few things so we can narrow it down?

  1. The request ID from the failed attempt (chat context menu in the top right > Copy Request ID)
  2. The developer console logs at the time it freezes (Help > Toggle Developer Tools > Console tab, look for red messages)
  3. What the indexing status shows at that time

Also, do you have any extensions installed, or is this a completely clean Cursor install?

Request ID:
3781ff0c-04ef-4d9c-a6a9-21c906d08fd9

Indexing status: codebase indexing shows 100%

This is not from a clean install, so I do have some extensions installed. I can re-run without, but I was able to reproduce this without any extensions previously.

There are some console errors at the time of chat hanging. This looks like the main culprit:
