I think I may be running into this issue. See my stack overflow question: http://stackoverflow.com/questions/42823842/vscode-cant-launch-node-app

@j55blanchet can you share our project so that I can have a look. I looked at the SO post but it doesn't provide enough information. Our launch doesn't specify a preLaunchTask hence I don't understand why launching will ask the task framework to start anything.

@isidorn are you requesting to run a task even if no preLaunchTask is defined?

[isidorn]

@dbaeumer no, I only talk to the task service if a preLaunchTask is defined in users launch.json

@isidorn @dbaeumer I was being stupid, and had the wrong task selected in the debug mode dropdown. Sorry for the false alarm!

[dbaeumer]

@j55blanchet thanks. I never the less added code to avoid the exception.
