ERR_MODULE_NOT_FOUND : vscode-jsonrpc/node.js

[LasseAtSparkron]

Im getting some errors after trying to install the latest version of squad. (0.8.20) at the time.

Error [ERR_MODULE_NOT_FOUND]: Cannot find module 'C:\Users\x\AppData\Roaming\npm\node_modules@bradygaster\squad-cli\node_modules\vscode-jsonrpc\node' imported from C:\Users\x\AppData\Roaming\npm\node_modules@bradygaster\squad-cli\node_modules@github\copilot-sdk\dist\session.js
Did you mean to import "vscode-jsonrpc/node.js"?

}

Node.js v24.14.0

I tried to upgrade using npm install -g @bradygaster/squad-cli

also tried an older version npm install -g @bradygaster/squad-cli@0.8.18

but i keep getting the same error when ever i type "squad" or "squad version"

I was working an hour ago before trying to upgrade :)

is there anything i can do to reset the npm, anyone have any suggestions ?

I tried adding it using : "npm i vscode-jsonrpc" but still getting the error.

anyone else having the same issue ?

Have just tried "npm install -g @bradygaster/squad-cli@0.8.22" version aswell

Found a temp workaround.

Editing:
C:\Users\x\AppData\Roaming\npm\node_modules@bradygaster\squad-cli\node_modules@github\copilot-sdk\dist\session.js

change:
import { ConnectionError, ResponseError } from "vscode-jsonrpc/node";

to:
import { ConnectionError, ResponseError } from "vscode-jsonrpc/node.js";

Hey @LasseAtSparkron — this is the same root cause as #265, which you also filed (thank you for both reports!).

What's happening: @github/copilot-sdk@0.1.32 has a broken ESM import — session.js references 'vscode-jsonrpc/node' instead of 'vscode-jsonrpc/node.js'. Node 24 enforces strict ESM and rejects it. This is an upstream bug: github/copilot-sdk#707

Workaround right now (v0.8.23):

The global install does work on v0.8.23 — our postinstall script patches the broken file. If you're still seeing the error after npm install -g @bradygaster/squad-cli@0.8.23, try:

1. Fully uninstall first: npm uninstall -g @bradygaster/squad-cli
2. Clear npm cache: npm cache clean --force
3. Reinstall: npm install -g @bradygaster/squad-cli@0.8.23

The key is that the postinstall script must run — it patches the broken import in the copilot-sdk. If npm uses a cached version, it may skip postinstall.

npx will NOT work even on 0.8.23 — npx caches packages and skips postinstall scripts, so the patch never applies. Use global install instead.

Fix coming in v0.8.24: We have added a runtime intercept (Module._resolveFilename) that fixes the broken import at startup — no postinstall dependency. This means npx, global install, and local install will all work. PR is up: #268.

Tracking in #265. Will close this discussion once the fix ships.
