openclaw - 💡(How to fix) Fix v2026.3.31: Dashboard returns 500 Internal Server Error on GET / [18 comments, 15 participants]

After updating to 2026.3.31, the dashboard at http://127.0.0.1:18789/ returns 500 Internal Server Error on every request. The gateway starts correctly (Telegram bots connect, WebSocket works, TUI works), but the HTTP handler crashes before serving any response. 3. curl http://127.0.0.1:18789/ returns 500 Internal Server Error

• Nothing is logged for the 500 — error happens before logger kicks in

TL;DR

The 500 Internal Server Error on the dashboard at http://127.0.0.1:18789/ may be related to issues with the HTTP handler or missing dependencies, and verifying the installation and dependencies of [email protected] could help resolve the issue.

Guidance

• Verify that all dependencies, including grammy, @grammyjs/runner, @grammyjs/transformer-throttler, and @buape/carbon, are correctly installed and up-to-date.
• Check the installation of [email protected] and ensure that node-addon-api is available, as the --ignore-scripts flag may have skipped important installation steps.
• Confirm that dist/control-ui/index.html is correctly served by the HTTP handler and that there are no issues with file system permissions or access.
• Consider reinstalling [email protected] without the --ignore-scripts flag to ensure that all scripts are executed correctly.

Example

No code snippet is provided as the issue does not specify a particular code-related problem.

Notes

The issue may be related to the use of the --ignore-scripts flag during installation, which could have skipped important setup or configuration steps. Additionally, the missing dependencies and [email protected] native build failure may be contributing factors.

Recommendation

Apply workaround: Reinstall [email protected] without the --ignore-scripts flag and ensure that all dependencies are correctly installed and up-to-date, as this may resolve the issues with the HTTP handler and missing dependencies.
