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.

Beginne mit src/extension.ts und dem im Stacktrace gezeigten Aufruf initializeFromJsonFile und untersuche anschließend den referenzierten Wrapper für die Extension-Telemetrie. Reproduziere den Start des Extension Development Host mit dem Beispiel-Java-Projekt und verfolge den Fehler mit dem Instrumentierungsschlüssel. Erledigt ist die Aufgabe, wenn die Extension ohne diesen Fehler aktiviert wird und eine Debugsitzung startet.
