if you need a Vue CLI setup to reproduce the problem, please provide a link to an actual repository.

The problem is quite simple, the type errror message in a render function is unfortunately not very helpful as it's too large.

Your code should look like this:

  setup(props, { slots }) {
    return () => {
      return h(TestComponent, { submit: props.submit! }, () =>
        slots.default ? slots.default() : undefined
      )
    }
  }

you are not passing the prop submit, which is required by TestComponent.

The problem is a bit better visible in a template:

And when you pass the prop, you realize it could still be undefined:
