"The string to replace was not found in the file." Every time

Describe the Bug

It seems every time Cursor tries to use this feature, I get this error. And sometimes I have to specifically tell it to not try to use string replace for it to be able to continue.

Steps to Reproduce

I just prompt the AI and it seems anytime it tries to do string replace, it fails. I have private mode on, not sure if that is needed to use it.

Operating System

MacOS

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, sorry about this!

If possible, can you share:

  • which model you are using
  • if this still happens in a brand new chat, or only in existing ones
  • a request ID for a chat that has a bad find and replace attempt (privacy mode off please!)
  • a screenshot of a failed attempt at this
