Upwork - how to prepare for JavaScript tests?

Question

React

Upwork got an order for Vue.js + Vuetify.js.
I wanted to respond, but the customer (I understand correctly - did he set such a condition himself?) Set a requirement for the performer - a qualification test is necessary in order to be able to respond.
And how to pass it then? This test? This is a JavaScript test, as far as I understand correctly?

Answer 1

Cannot find "/umd/react-dom.devel..." in [email protected]

Answer 2

what does the condition look like, show the screen?
maybe he meant that those interviews would need to be passed
