Azure Functions Core Tools throwing error with default function: can't find ../azurefunctions/functions.js


I reinstalled Windows 10 several weeks back and had to reinstall all the tools. Not being a professional, I just went with the latest versions of everything and today updated the Core Tools.

I'm currently at

  • Node: 8.11.1
  • Core Tools: 1.0.11

I just created a new function app and function and am getting the following error when I try to call the URI through Postman.

Solution

  • It seems a bug on the latest v1.0.11 function core tool.

    I install it using npm on my side, and reproduce the error after triggering a js httptrigger(template).

    The error seems to occur only when using js trigger, as I create a js blobtrigger same error occurs. For c#, test on httptrigger and blobtrigger, both work.

    I have opened an issue on github and waited for Azure team's reply.
