I still have this issue using --continue on latest version and twice esc does not resolve it, I submitted /bug with ID 1421edcf-5be3-4dcc-8723-6259a5ab1e42

I have the same issue. usually happens with git commands
for example:

Bash(git log --oneline -3)
  ⎿  3c38b28 lint fix
     2c33a29 fix lint errors
     444c313 chore: migrate from flake8 and black to ruff for linting and
     … +1 line (ctrl+r to expand)
  ⎿ API Error: 400 {"type":"error","error":{"type":"invalid_request_error
    ","message":"messages.175: `tool_use` ids were found without

    `tool_use` block must have a corresponding `tool_result` block in the

Just received the same 400 API Error:

API Error: 400 {"type":"error","error":{"type":"invalid_request_error","message":"messages.5.content.12: `thinking` or
    `redacted_thinking` blocks in the latest assistant message cannot be modified. These blocks must remain as they were in the

I'm on 1.0.51

same error. Im in wsl

Still happening! Really annoying.

Same here

Same for me

The same goes for me! What are you doing?! Could you tell us why you closed the issue without resolving it?

Same here with docker-compose file that has some environment variables.

This still happening for me on node v22, when I use it in node v20 it works.

We've resolve the root cause for this issue in 1.0.21 (claude update and claude --version). To recover a stuck session hit "esc" twice and rewind back to before the error.

rewinding does not work either. whats the solution here please? i have tried everything and nothing works

Same for me

Just hit this on v1.0.72. No matter why I say, it thinks briefly that hits this error.

same here.

same here. got this error first time 2 times today on MAX plan. I tried to /exit and go back to the chat with claude -c, but it didn't work. I didn't hit my limits. Worked /exit and then claude code but I lost all my context.

My workaround was to Esc-Esc and rewind the conversation to the stage before the error first occurred.
