openclaw - 💡(How to fix) Fix Telegram channel fails to load: Cannot find module grammy (missing bundled dep) [1 comments, 2 participants]

Bug description

The Telegram channel fails to load on startup with the following error:

[channels] failed to load bundled channel telegram: Cannot find module 'grammy'
Require stack:
- /home/mike/.npm-global/lib/node_modules/openclaw/dist/extensions/telegram/send-t4GTTdHF.js

The extension file dist/extensions/telegram/send-t4GTTdHF.js uses:

import * as grammy from "grammy";
import { Bot, HttpError } from "grammy";

and also imports @grammyjs/runner and @grammyjs/transformer-throttler.

These packages exist in ~/.openclaw/plugin-runtime-deps/openclaw-<version>/node_modules/ (installed by memory-core plugin), but are not present in openclaw's own node_modules/, where the bundled channel extension expects to find them.

Steps to reproduce

1. Fresh install or openclaw update to v2026.4.29
2. Start the gateway: systemctl --user start openclaw-gateway
3. Observe logs: [channels] failed to load bundled channel telegram: Cannot find module 'grammy'

Environment

• OpenClaw: 2026.4.29 (a448042)
• OS: Ubuntu Linux 7.0.0-14-generic x64
• Node.js: 22.22.2
• Install method: npm global (npm install -g openclaw)

Workaround

Manually symlink the missing packages from plugin-runtime-deps into openclaw's node_modules:

DEPS=~/.openclaw/plugin-runtime-deps/openclaw-2026.4.29-d95749a2df8f/node_modules
OCL_MODS=~/.npm-global/lib/node_modules/openclaw/node_modules

ln -s $DEPS/grammy $OCL_MODS/grammy
mkdir -p $OCL_MODS/@grammyjs
ln -s $DEPS/@grammyjs/runner $OCL_MODS/@grammyjs/runner
ln -s $DEPS/@grammyjs/transformer-throttler $OCL_MODS/@grammyjs/transformer-throttler

This symlink is lost after each openclaw update.

Expected behavior

grammy, @grammyjs/runner, and @grammyjs/transformer-throttler should be declared as dependencies of the telegram bundled channel (or shipped as part of openclaw's own node_modules) so the channel loads without manual intervention.
