Initial error:

TL;DR

The most likely fix is to ensure the grammy dependency is properly installed and configured for the openclaw Telegram plugin.

Guidance

• Verify that grammy is installed by running npm ls -g grammy and install it if necessary using npm i -g grammy.
• Check the openclaw configuration to ensure that the Telegram plugin is correctly set up and that the grammy dependency is referenced correctly.
• Run OPENCLAW_PLUGIN_LOADER_DEBUG_STACKS=1 openclaw plugins list --json to debug the plugin loading process and identify any issues with the grammy dependency.
• Consider rolling back to a previous version of openclaw, such as 2026.4.15, as a temporary workaround if the issue persists.

Example

No code snippet is provided as the issue is related to dependency installation and configuration rather than code implementation.

Notes

The issue may be related to the "bundled plugin runtime dependency repair" mentioned in the 2026.4.21 changelog, which could be causing issues with the grammy dependency. Further investigation is needed to determine the root cause of the issue.

Recommendation

Apply the workaround by rolling back to [email protected] until a fix is available, as this version is known to work correctly.
