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.

 

The errors you’re seeing now come from conflicting or corrupted Fabric/Synapse extensions in VS Code, not from the network. That’s why you get messages like extensionIsReady not found and why only the Microsoft Runtime PySpark kernel shows up instead of the proper synapse-spark-kernel. When the wrong extension loads, the debugger can’t initialize.

 

Uninstall all Synapse/Fabric extensions from VS Code, delete their folders under your .vscode/extensions directory, then reinstall just the Fabric Data Engineering (Preview) extension. After reinstall, sign back into Fabric in VS Code, that should refresh the environment and surface the correct Spark kernel so debugging can start normally.

Hi v-hashadapu,

Thanks once again for your reply. I have now tried following your instructions, by uninstalling all fabric related vs code extensions. It still does not work, I am still only able to see the Microsoft Runtime PySpark kernel, and the debugging does not work. 

 

I don't see the error: "ExtensionIsReady not found" anymore.

 

But I still get the error:

[error] TypeError: Cannot read properties of undefined (reading 'split')
 


I don't have the Fabric Data Engineering (Preview) extension avaliable to me, only the Fabric Data Engineering extension, should I try with the pre-release version of the extension?
