Note that I am properly returing a position in my debugHover here
@jrieken might you have the clue what is the issue here

@isidorn this means someone requests the hover without providing a position. I am pretty sure this is debugging itself, via this https://github.com/Microsoft/vscode/blob/200d30e467f9020cc2de8c5cbb2cb2c1fd1831ce/src/vs/workbench/parts/debug/electron-browser/debugEditorContribution.ts#L418

@jrieken thanks! You were correct I was wrongly requesting the hover
