VSCode Jupyter integration: ts and deno enabled at the same time?

[neongreen]

❯ deno --version
deno 1.41.0 (release, aarch64-apple-darwin)
v8 12.1.285.27
typescript 5.3.3

❯ code --version
1.87.0

arm64

I created a new Jupyter notebook in VSCode and switched kernel to Deno.

It looks like Deno is working -- but I'm also getting TS errors that I shouldn't be getting with Deno.

Am I doing something wrong?

Sample code:

const fileContents = await Deno.readTextFile("");

Note: this goes away if I save the notebook in a workspace. Only shows up if I create a new editor with a notebook but don't save it.

Oops, should've filed in vscode_deno I guess
