this is also happening to me - just started today

Same error for me

same

same, and no more error messages

+1 the same error !

I also got that error very frequently and I asked Claude Code, here is its response:

The "Error editing file" occurred because I tried to use the Edit tool on files I hadn't read first in that session. The Edit tool requires reading a file with the Read tool before making changes to it - this is a safety feature to ensure I understand the file's current state before modifying it. I should have been more careful to always read files first, but the errors didn't block our progress since I caught and corrected them by reading the files before editing.

This sounds plausible to me.

any idea on fixing that - guys?

I had this issue in the past, then it went away, and now today clause code is unusable, throwing this error over and over. I closed, reopened, tried a simple 'add one character to index' prompt and same issue.

currently completely broken.

Agree, happens every session for over a week. Burning usage.

Same for me, still hapenning, making claude code barely usable and causes issues - e.g. duplicated code - once it adds it using "update" and later has error anyway and appends it in end of file

Error editing file
Error reading file
Error... the file ops are broken

+1 same error

⏺ Update(test/repository/storage_upload_helper_test.dart)
  ⎿  Error editing file

⏺ Update(test/repository/storage_upload_helper_test.dart)
  ⎿  Error editing file

Same happening here. It is sporadic and seem random. File claude is trying to modify is never locked nor opened by another app.

Why this is an important issue is that CLAUDE does not seem to notice the error that it could not write the modifs. So we end up with partial/broken modifs at the end.

deleting the file and recreating it worked for me

I found that disabling vscode formatOnSave "fixes" it. It's not a long term solution, but I'm feeling like it's a race with file formatters and CC. I haven't tried running CC outside of vscode.

But absolutely, this problem comes and goes, and then it sort of gets past using cat or sed. It's a pretty big problem.

Any update on this? It's a real problem and as discussed on https://github.com/anthropics/claude-code/issues/6595 (which I think is a dup of this), it seems to have nothing to do with vscode's formatOnSave or prettier or anything like that.

same error for me! it really annoys me
