I’m not sure what the first error means here

Package code to reproduce

Error

Execution Error: Not able to guess root component: RootCircuit has no children (use circuit.add(...)). "entrypoint": "entrypoint.tsx" is set in the runner configuration, entrypoints must contain "circuit.add(...)", you might be looking to use mainComponentPath instead if your file exports a component.

@0hmX filename should be circuit.tscircuit.tsx? Shouldn't it be example.circuit.tsx or just example.tsx

I think you gave the wrong repro link

It’s the same code — I double-checked. Also, I’m not sure why the file name would matter.

After stopping and restarting the server, the issue seems to have disappeared. Good for us 🧀
