eslint — Cannot read property ‘value’ of undefined

2017 January 18

Are you seeing ESLint throwing an error like

Cannot read property 'value' of undefined
TypeError: Cannot read property 'value' of undefined
    at getStarToken (.../node_modules/eslint/lib/rules/generator-star-spacing.js:68:25)
    ... bunch more stack trace here

It might be that you’ve put async on a named function, and ESLint doesn’t like it. I made ESLint happy by making the function a fat-arrow anonymous function with async on it, and assigning it to a const with the name I wanted.

eslint/eslint issue: Async function declaration
babel/babel-eslint issue: Remove the ast changes for async/await when ESLint supports it
