openclaw - 💡(How to fix) Fix Missing @slack/web-api and @slack/bolt dependencies cause HTTP 500 on all requests [1 comments, 2 participants]

On a fresh install of [email protected], every HTTP request to the gateway returns 500 Internal Server Error — including the Control UI, API endpoints, and RPC. WebSocket connections work fine. However, neither @slack/web-api nor @slack/bolt are listed in dependencies or optionalDependencies in package.json. If these packages are not already present (e.g., from a previous install or another package), the static import fails, and the top-level HTTP request handler catches the error with a bare catch {} that returns 500 with no logging. 4. Visit http://127.0.0.1:18789/ → 500 Internal Server Error 3. At minimum, add error logging to the catch block so the issue is diagnosable without patching the source

TL;DR

Install @slack/web-api and @slack/bolt as dependencies to resolve the 500 Internal Server Error issue.

Guidance

• Verify that @slack/web-api and @slack/bolt are not already installed globally by running npm ls -g @slack/web-api @slack/bolt.
• Add @slack/web-api and @slack/bolt to the dependencies section in package.json to ensure they are installed with the project.
• As a temporary workaround, install @slack/web-api and @slack/bolt globally using npm i -g @slack/web-api @slack/bolt.
• Consider using dynamic imports for Slack modules to avoid loading them when not needed.

Example

No code snippet is necessary in this case, as the solution involves installing dependencies or modifying the package.json file.

Notes

This solution assumes that the issue is caused by the missing dependencies @slack/web-api and @slack/bolt. If the issue persists after installing these dependencies, further debugging may be necessary.

Recommendation

Apply the workaround by installing @slack/web-api and @slack/bolt as dependencies, as this is the most straightforward solution to resolve the issue.
