I created a Visual Studio Team Services task in Node and when I execute on a Windows based agent I get the following error:

Solution:
Statically link the q module in your node_modules folder.
Explanation:
When you publish a task to VSTS using TFX everything in the task path is uploaded with the task. Therefore, make sure the q module is included in that upload. I create a batch script that copies the desired files to a temp directory then run the upload command from TFX from that folder. That way I do not upload my entire node_modules folder. It is also recommended that statically link vso-task-lib. Below is an example of my folder structure. The tools folder contains files I need access to for my task to execute i.e. docker.exe.
