error raised with Brave

[Grip]

Hi,
this would be a great app but I cannot make it work (alas with Brave which is the only browser I can use).

When I execute it on my pinterest profile it returns an error:

in the console I see the message/error:

VM245:75  GET https://www.pinterest.com/resource/BoardsResource/get/?data=%7B%22options%22%3A%7B%22username%22%3A%22fabiotavano%22%2C%22field_set_key%22%3A%22detailed%22%7D%7D 403 (Forbidden)

[Violation] 'load' handler took 9975ms

and it refers to this piece of code

function c(e, t, o) {
		var r = new XMLHttpRequest;
		r.onload = function() {
			r.status >= 200 && r.status < 300 ? o(JSON.parse(r.responseText)) : (alert("An error has occurred."), console.log(JSON.parse(r.responseText)))
		}, r.open("GET", "/resource/" + e + "Resource/get/?data=" + encodeURIComponent(JSON.stringify({
			options: t
		}))), r.setRequestHeader("X-Requested-With", "XMLHttpRequest"), r.setRequestHeader("Accept", "application/json, text/javascript, */*, q=0.01"), r.send()
	}

Hope it'll help you to find the cause with this issue.

Regards!!
