Error:
var z = JSON.parse(bisas)
^
SyntaxError: Unexpected token o in JSON at position 1
Code:
for(let m in base.bs){
if(base.bs[m].notifications == true) {
console .log(base.bs[m].id)
const bisas = request(" https://api.vk.com/method/messages.isMessagesFromG... ");
var z = JSON.parse(bisas)
let allowed = Number(z.response.is_allowed)
console.log(allowed)

>Unexpected token o in JSON at position 1
This is an invalid JSON format error, that is, something else arrives.
