Validated. I did the following:

1. Install VS Code 1.54 and the March release (2021.3.x) of the Jupyter extension on the marketplace
2. Run `Specify local or remote Jupyter server for connections’ to pick AML compute remote jupyter server
3. Open a blank notebook with the remote connection
4. Upgrade to VS Code 1.55.1 with the same 2021.3.x release of the Jupyter extension
5. Run ‘Specify local or remote Jupyter server for connections’ and verify the error message comes up:
6. Install the Jupyter vsix from this morning’s bug bash
7. Run ‘Specify local or remote Jupyter server for connections’ and verify the quickpick comes up with no error message 🎉

@clayms we’re planning to make this fix available in a point release early next week so I’m going to go ahead and close this issue. Please keep an eye out for that release, which should resolve this issue. Thanks for bringing this to our attention!

The following seems to have fixed the issue, however, I don’t think updating VS Code should cause this much hassle.

1. Deleted the following from my named.workspace file,

	"settings":  {
		 "jupyter.jupyterServerType": "remote"
	}

1. Restarted VS Code,
2. <kbd>ctrl</kbd>+<kbd>shift</kbd>+<kbd>p</kbd> then Jupyter: Clear Jupyter server list,
3. Ran python code with <kbd>shift</kbd>+<kbd>enter</kbd> in the local default python interpreter,
4. <kbd>ctrl</kbd>+<kbd>shift</kbd>+<kbd>p</kbd> then Jupyter: Specify local or remote Jupyter server for connections.
