[BUG] "Error executing Claude query: Claude Code process exited with code 1" when executing using Typescript Claude Code SDK in VSCode Typescript debug terminal

Environment

• Platform (select one):
• [x] Anthropic API
• [ ] AWS Bedrock
• [ ] Google Vertex AI
• [ ] Other: <!-- specify -->
• Claude CLI version: 1.0.61 (Claude Code)
• Operating System: Using Devcontainer mcr.microsoft.com/devcontainers/typescript-node:1-22-bookworm which uses Debian GNU/Linux 12 (bookworm)
• Terminal: bash

Bug Description

Claude Code SDK runs just fine when running in a regular, non-debug shell with no debugger attached (kudos on job well done)

However, when running in Typescript debug console, it fails with Error executing Claude query: Claude Code process exited with code 1" when executing using Typescript Claude Code SDK and a non-useful stack trace.

Expected behaviour

Should run when debugging in VSCode

If it fails, should show useful error

Actual behaviour

Does not run when debugging in VSCode

When it fails, does not show useful error

Additional Context

    # i run using `pnpm dev`
    "dev": "pnpm dev:client & pnpm dev:server & wait",
    "dev:client": "vite serve src/client --host",
    "dev:server": "tsx --env-file=.env --watch src/server/server.ts",
