TypeError: o.provideFileDecoration is not a function

[Morriz]

I see this error after startup which seems unrelated to extensions:

I am running node 14, but vscode brings it's own version, right?

• VSCode Version: 1.51.1
• OS Version: OSX

Steps to Reproduce:

1. Open vscode an navigate to Output tab and select Log (Extension Host)
2. see the error

Does this issue occur when all extensions are disabled?: No

nvermind, it was the node extension, duh! Will take it there...

[Morriz]

premature closure as the node plugin is built in, reopening...

[jrieken]

What node extension would that be?

[Morriz]

I was referring to ...workbench/services/extensions/node/extensionHostProcess.js...

[jrieken]

Ok, this error happens when we call into an extension - in particular case an extension that uses a proposed API. Are you using LiveShare by any chance? Can you retry with that disabled?

[jrieken]

ping @Morriz

ping @lostintangent - looks like LiveShare uses a proposed API that has changed
