Trying to run examples, getting ‹TypeError: registry.handler is not a function› errors
❓type: question🌐engine: html5
Hi all,
I’m new to Rivet and have been trying to run the examples since Sunday without much success. Depending on the example, I’m hitting different issues.
Are the examples currently being worked on? If so, is there one known to work, just to verify that everything is set up correctly on my machine? Alternatively, is there any additional setup required (e.g. environment variables from the Rivet dashboard) before running the examples?
For example, following the instructions here:
https://www.rivet.dev/templates/actor-actions/
Both backend and frontend start correctly, and the UI loads at http://localhost:5173. However, as soon as the page is opened, the backend logs repeatedly show:
At the same time, the browser console shows 500 Internal Server errors when requesting
http://localhost:5173/api/rivet/metadata?namespace=default
Environment:
* Safari 26.2
* Apple M1 Max, macOS Tahoe 26.2
* Node.js v25.2.1
* npm v11.7.0
Any guidance on a known-good example or missing setup steps would be much appreciated!
