Problem Description

The playground runs and console.log prints as expected. However, when it's time to show the result in the editor, VS Code shows an error.

Steps to Reproduce

Except for using VS Code insiders, not sure.

Expected Results

The editor is open and the result is displayed

Actual Results

Additional Notes

It was all working fine, I went to lunch, came back and I started seeing this error every time I'd try to run a playground. I had to kill VS Code and reopen it to make it work again.

I had pizza for lunch, not sure that helps with reproducing the problem though.
