Please provide instrumentation key

Start with src/extension.ts and the initializeFromJsonFile call shown in the stack trace, then inspect the referenced extension telemetry wrapper. Reproduce the Extension Development Host launch with the sample Java project and trace the instrumentation-key failure. Done means the extension activates without this error and a debug session starts.

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
