What's Wrong?

Description:

Extension version: 2.1.129
Platform: Windows 11

Error:
Activating extension Anthropic.claude-code failed due to an error:
TypeError: The argument 'filename' must be a file URL object, file URL string, or absolute path string.
Received 'file:///home/runner/work/claude-cli-internal/claude-cli-internal/build-agent-sdk/sdk.mjs'

What Should Happen?

Problem:
The extension.js contains a hardcoded Linux path from the CI/CD build environment (/home/runner/work/...) that doesn't exist on Windows systems. This prevents the extension from activating.

Workaround:

Use claude CLI directly in terminal
Or use Claude Code in terminal mode instead of native UI
