Error at launch

[nashfive]

Hi!
I am on Tahoe 26.3 and Xcode 26.3.
I've installed node 25.8.0 via brew and then xcode-copilot-server via npm install -g.

When I try to launch xcode-copilot-server I get this error:

xcode-copilot-server
node:internal/modules/run_main:107
    triggerUncaughtException(
    ^

Error [ERR_MODULE_NOT_FOUND]: Cannot find module '/opt/homebrew/lib/node_modules/xcode-copilot-server/node_modules/vscode-jsonrpc/node' imported from /opt/homebrew/lib/node_modules/xcode-copilot-server/node_modules/@github/copilot-sdk/dist/session.js
Did you mean to import "vscode-jsonrpc/node.js"?

}

Node.js v25.8.0

Any ideas how to fix this?

@nashfive It's a bug in the Copilot SDK - github/copilot-sdk#734

In the meantime, I have pushed a fix in v4.0.4 so please update to it.
