Why can wikiquote api return 404 when using jsonp?

Question

JavaScript

Greetings, there is a task to get information from wikiquote using api and jsonp, the solution was applied:
pastebin.com/PgtvmHhX
It returns 404, but if you enter https://en.wikiquote.org/w/api.php?action=parse&ti. .. the json I need is displayed in the browser line. To check, in the ajax request I replaced the url with https://en.wikipedia.org/w/api.php?action=parse&ti... ( pastebin.com/EptDz7pd ) it returns status 200 and the requested json. What could be wrong?
