I’m running Z2JH through AWS EKS cluster, though that shouldn’t be any issue, as my understanding is these debugger runs through the kernel itself?

From the terminal within jupyter

```auto

I’ve also checked the `kernel.json` contents of all kernels in `/usr/local/share/jupyter/kernels`, but they all contain `"debugger": true`.

The `-` on top of the debugger suggests that it is not connected to the notebook. If you click on `...` in toolbar, does the debugger icon have a dot indicating that the debugger is enabled or not?
