Error Error: Evaluation failed: TypeError: Cannot convert undefined or null to object

[YoranBrondsema]

I'm attempting to run the codemod on a component in my app but I'm getting an error with (I think) puppeteer. Any thoughts about what might be going wrong?

yoran $ npx ember-native-class-codemod http://localhost:4200 app/components/inplace-editor/component.js
