VSCode - Setup Issues for Code Insights

I’m trying to get Code Insights working with the vscode-coldbox extension.

It seems to work with

handler then press return and a handler skeleton appears

But when I hover over a function

event. or event()

I don’t get anything. AFAIK code insights are there to show information about the function. Pressing F12 for definition also comes up blank. Am I expecting correctly?

I’ve checked all the settings, searched the web but can’t find anything.

TIA

Tony
