Please provide instrumentation key

I'm trying to debug the java-debug server and for that I've launched vscode-java-debug plugin, in which after launching its "Extension Developement Host" I've opened my sample Java project.

But when I'm trying to launch my sample project vscode-java-debug prints out the following:

{affectsConfiguration: ƒ}
Error: Please provide instrumentation key {stack: 'Error: Please provide instrumentation key

And in result no debug session starts.

Bắt đầu với src/extension.ts và lệnh gọi initializeFromJsonFile được hiển thị trong stack trace, sau đó kiểm tra telemetry wrapper của extension được tham chiếu. Tái hiện việc khởi chạy Extension Development Host với dự án Java mẫu và truy vết lỗi instrumentation key. Hoàn tất khi extension kích hoạt mà không gặp lỗi này và một debug session được bắt đầu.
