I’m new to the web, I made a page with a form for entering name and password, but when I try to get data, instead of json I get an html page and an error '<', "<!doctype "... is not valid JSON. Also, my data should be saved in cookies by credentials: 'include', but this is not happening and I don’t understand why. I’m using nuxt.js and creating an ‘spa’ project. Please help me if you now where i’m doing wrong.
