Error with notebook debugging is vs code.

Hi, I’m trying to debug Fabric notebooks in VS Code, but keep running into problems.  It does work running the notebook normally using remote compute.  I’ve followed the Microsoft Learn tutorials...

Hi TobiasKon , Thank you for reaching out to the Microsoft Community Forum.

 

Debugging Fabric notebooks won’t work in the VS Code web experience yet, only the desktop Fabric Data Engineering extension supports it. The error you’re seeing almost always means your company firewall or proxy is blocking the WebSocket connection that debugging relies on. Fabric needs both HTTPS and WSS access to *.pbidedicated.windows.net without TLS inspection. If it works on a personal hotspot network but not on your work machine, that confirms it’s the firewall.

 

Use desktop VS Code, select the synapse-spark-kernel and have IT allowlist or bypass SSL inspection for https://*.pbidedicated.windows.net and wss://*.pbidedicated.windows.net. Once that’s done, the debug session should start normally.
