What's Wrong?

When using Claude Code VS Code extension v2, the claudeCode.claudeProcessWrapper option doesn't work for me with the default non-terminal mode.

For instance, even when setting claudeCode.claudeProcessWrapper to a direct path of non-wrapped Claude binary, /Users/nekketsuuu/.volta/bin/claude, Claude keeps showing waiting messages like "Marinating..." after sending a question.

It may be interesting that, after closing the extension pane and re-opening the pane, it has a record for successful response in its "Past Conversations" history. So the extension seems to have an issue around displaying its response, I guess.

What Should Happen?

The response will be shown as usual.

Error Messages/Logs

I can't find any logs about this. I'd appreciate if anyone suggests how to show internal logs of the VS Code extension.

Steps to Reproduce

1. Install Claude Code VS Code extension v2.
2. Set up like below:

``
"claudeCode.claudeProcessWrapper": "/Users/nekketsuuu/.volta/bin/claude",
"claudeCode.environmentVariables": [
{
"name": "CLAUDE_CODE_USE_BEDROCK",
"value": "1"
}
],
"claudeCode.useTerminal": false
``

Actually I'd like to choose my wrapper command for claudeProcessWrapper, but I found that this issue still happens when I set it to the plain claude command.

1. Open the Claude Code VS Code extension pane.
2. Ask something.
3. It will only show several waiting messages.
