yup.object().required() works fine - but adding a shape leads to always pass

I can confirm that doing what @Zerebokep said works perfectly. Here is how to do it:

user: yup
    .object()
    .shape({
      name: yup.string().required(),
      avatarUrl: yup.string().required(),
    })
    .default(undefined) // 👈 
    .required(),

I face the same issue.

edit: using .default(undefined) on the required object fixed my issue, objects default to {}, which is the reason why .required doesn’t throw a validation error.
