`this.doc` is possibly undefined

Please fill-in this template.

• I have a question that is specific to this extension; thus, inappropriate for the main EditorConfig issue tracker.
• I tried running code --disable-extensions and the issue did NOT present itself.

Delete the following condition if it doesn't apply to your case:

If the extension is not picking up the expected configuration for a file:

• I tried npm install editorconfig -g and ran editorconfig [file-in-question] and the configuration was what I expected. If not, please file on the editorconfig-core-js issue tracker.

Issue

	Visual Studio Code	editorconfig-vscode
Version	1.30.2	0.12.7

Root .editorconfig File

does not exist but the problem is not related with the config file.

Are there any other relevant .editorconfig files in your project? Yes / No

Visual Studio Code Setting	Default	User	Workspace
editor.insertSpaces	true	____	____
editor.tabSize	4	_	_
editor.trimAutoWhitespace	true	____	____
files.autoSave	"off"	"___"	"___"
files.insertFinalNewline	false	_____	_____
files.trimTrailingWhitespace	false	_____	_____

File opened

./.../*.ts

Expected behavior

It outputs no error from the extension host.

Actual behavior

It throws an error saying that

 ERR Cannot read property 'fileName' of undefined: TypeError: Cannot read property 'fileName' of undefined

Additional comments or steps to reproduce

I just focused on the editor.

I've found that DocumentWatcher.js#L52 can lead to this behavior if this.doc is not set.
