Hi Tim, I can see your build fails coming up in our logs, our developers are looking into it and will reach out to you via the chat once we have a solution. In case it helps just now it looks like an issue related to referencing something inside a dynamic tile from outside it - the most likely culprit is an action referring to an element that’s inside a tile.
Troubleshooting build fails is definitely something we’re focused on improving because we know it’s tough right now. The team is working on a number of improved error reporting and debugging features you’ll hopefully see in the platform soon. In the meantime don’t hesitate to ask via the chat in the editor and we’ll look into any issues you’re having!
