after installation getting errors

[Anima-t3d]

I installed the boost and restarted claude, but now Claude is getting stuck:
Claude gets stuck (tokens not increasing), press esc and see Cannot read properties of undefined (reading 'message')

A while after posting the original message it seemed to "work" (auto approve/block and unsure), but still getting the non-blocking error messages.

According to claude itself:

| | The Issue: The hook is configured to run ccb auto-approve-tools, but the error           │ │
│ │ message mentions claude -p --output-format json. This suggests:                          │ │
│ │   - Either the hook configuration was recently changed from claude to ccb                │ │

looking at the approval log, there have been several successful runs for tool approval but the approval error came in when running a Bash tool call.

could you try the following command to invoke ccb directly and let me know the output?

echo '{"session_id":"test","transcript_path":"/tmp/test","tool_name":"Bash","tool_input":{"command":"ls -la"}}' | node ccb auto-approve-tools

[Anima-t3d]

When running the above command in the project folder:

echo '{"session_id":"test","transcript_path":"/tmp/test","tool_name":"Bash","tool_input":{"command":"ls -la"}}' | node ccb auto-approve-tools
node:internal/modules/cjs/loader:1228
  throw err;
  ^

[yifanzz]

I incorrectly included the node command in there, could you try this:

echo '{"session_id":"test","transcript_path":"/tmp/test","tool_name":"Bash","tool_input":{"command":"ls -la"}}' | ccb auto-approve-tools

could you also make sure you are on the latest version by running npm install -g claude-code-boost@latest

[Anima-t3d]

Before running npm install -g claude-code-boost@latest :

I also get these errors:

Some updates to claude code related to tool calling, might be useful? https://claudelog.com/claude-code-changelog/#v1059

[Anima-t3d]

I got this, not sure if all this is helpful. I'm running this on a mac, tried reinstalling several times including user setting and project level setting. I also upgraded node to v22 but still have the same issues.

I have a similar issue. I get a lot of errors like

On a mac, node v22.14.0

[Anima-t3d]

@zoltarburger that specific resource issue might be claude api having issues. Do you have the other issues as well?
These kind:

      throw er; // Unhandled

same isse, even in latest version .. haha

[Anima-t3d]

I have not been using this hook since last post, I realised that you can use a pre-existing "allow list" that covers 99% of your usual approved calls. Most of my projects have 99% overlap in allowed tools so I just copy it over and collect more allowed tools over time 😅

that's mean this library is useless 🥱
