fresh install using npm install -g @bradygaster/squad-cli
or using the one off : npx @bradygaster/squad-cli gives error when using squads commands with the error message below.

There is a typo in the copilot-sdk\dist\session.js

missing the "js" file type, hence it keep getting errors.

Manually editing the file makes it work again:

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

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"?

    looks like it's the copilot-sdk dependency that was upgraded today, any chance to lock it to an older version until the dependency are fixet ?

    0.8.23 fixes this for me

    EDIT: It fixed me running npx squad init, but not just npx squad

    I tried aswell with the 0.8.23
    Works with the global version installed.

    uninstalling
    npm uninstall -g @bradygaster/squad-cli

    and running the one off makes it crash.

    npx @bradygaster/squad-cli

    Need to install the following packages:
    @bradygaster/squad-cli@0.8.23
    Ok to proceed? (y) y

    @MatthewSteeples and @LasseAtSparkron thanks for reporting this and iterating. I fired up a codespace and tried this with 0.8.22 and still had the error, so i re-pushed 0.8.23 and tried it and the error went away. Note - i did not try over-the-top of the failing 0.8.22 release, i just fired up a new codespace and tried again.

    Can you confirm 0.8.23 "just works" with a new repo/folder whereas upgrading from 0.8.22 to 0.8.23 does not fix it?

    Root Cause Analysis

    The bug is upstream in @github/copilot-sdk@0.1.32 — session.js imports 'vscode-jsonrpc/node' instead of 'vscode-jsonrpc/node.js'. Node 24+ enforces strict ESM resolution and rejects the bare import.

    v0.8.23 partially fixed this:

    • ✅ npm install -g @bradygaster/squad-cli works (postinstall script patches the file)
    • ✅ npx squad init works (lazy-load means init never imports copilot-sdk)
    • ❌ npx squad (no subcommand) still crashes — npx caches packages and skips postinstall, so the patch never runs

    Workaround (for users on v0.8.23)

    Option 1 — Use global install instead of npx:

    npm install -g @bradygaster/squad-cli
squad init

    Option 2 — If you must use npx, clear the cache first:

    npx --yes --package @bradygaster/squad-cli@0.8.23 squad init

    If that still fails, clear the npx cache:

    # Find your npx cache
npm config get cache
# Delete the _npx folder inside it, then retry

    Option 3 — Manual patch:
    Find the cached copilot-sdk file and change vscode-jsonrpc/node to vscode-jsonrpc/node.js in node_modules/@github/copilot-sdk/dist/session.js.

    Fix coming in v0.8.24

    We've added a runtime Module._resolveFilename intercept that rewrites the broken import at startup — no postinstall needed. This fixes all installation methods (global, npx, local). Tracking in commit 09e745f.
