How to fix Yup cannot read property object of undefined

If you’re using TypeScript with Yup, you might be running into this error:

TypeError: Cannot read property 'object' of undefined

And this is what your code may look like

import yup from 'yup';

const schema = yup.object().shape({});

To fix the error message above, make sure you have types for Yup installed.

npm i -D @types/yup

The next thing to update is how you import Yup into your TypeScript file

import * as yup from 'yup';

That’s it!
