Why is vue-resource returning a 500 error on Windows?

Question

Vue.js

Good afternoon.
I'm making a page using VUE. Using GET vue-resource , I request JSON data that Yii2 returns. So, everything goes smoothly on MacOS (Safari, Chrome), I open the page on Windows and, in response to a request, an error 500 is displayed in the console and the requested data goes on, i.e. Yii2 returns what you need without errors (if you go directly to the Yii2 URL, the page opens without errors and the data is displayed). I broke my head, I don’t understand why this is happening.
This is the error I always get GET localhost/purchases/api/price 500 (Internal Server Error) vue-resource.min.js?v=1536320897:7
I also tried using Axios, and the same thing:
GET localhost/purchases/api /price500 (Internal Server Error) spread.js:25
All figured out)

Answer 1

Understand with the server why it reacts so violently to the request.
