Console.warn is not a function

Im using xstate inside one of our workflows, a few days ago they updated their repo to add a console.warn statement inside of the createMachine function.

This caused the workflow to start failing with the below error.

console.warn is not a function 
TypeError: console.warn is not a function
    at Module.createMachine (webpack-internal:///./node_modules/xstate/es/Machine.js:22:13)
    at eval (webpack-internal:///./dist/apps/customer-interpreter-app/assets/lib/workflows/flow-renderer.js:31:36)
    at step (webpack-internal:///./node_modules/tslib/tslib.es6.js:129:23)

    at fulfilled (webpack-internal:///./node_modules/tslib/tslib.es6.js:100:58)

I fixed this short term by just monkey patching console.warn to console.log.

What is the correct way to deal with something like this when running workflows in typescript.

Currently, we only define console.log in the Workflow vm:
