VS-Code Extension: vscode.window.activeTextEditor == undefined

I wrote an Visual Studio Code extension. Based on this example: https://github.com/Microsoft/vscode-extension-samples/tree/master/previewhtml-sample

var editor = vscode.window.activeTextEditor;
if (!editor) {
    console.log("No open text editor");
}

This works fine if i open a 2MB File. But not if the file is 5MB or larger.

But if I copy (Ctrl+C,Ctrl+V) a 10MB into a new editor it will work and is prety fast. Has anyone an idea what kind of limitation this is?

Or is there perhaps a work around by some how let user choose a file in command. To directly read the file?

This was addressed upstream in this issue

The root cause was that VS Code did not properly create text editors for files over a certain size. That size limit has since increased but you still may run into this limitation for very large files
