I am trying to practice For loop and I am new in coding in general. When I try to run my program it gives me an error that says "No debugger available, can not send 'variables'. What should I do to fix it?

function trekkingMania(input) {
let index = 0;
let groups = Number(input[index]);
index++;

let musala = 0;
let monBlan = 0;
let kilimanjaro = 0;
let k2 = 0;
let everest = 0;
let totalPeople = 0;

for (let i = 0; i < groups; i++) {
    let climbers = Number(input[index]);
    index++;

    totalPeople = totalPeople + climbers;

    if (climbers <= 5) {
        musala = musala + climbers;
    } else if (climbers >= 6 && climbers <= 12) {
        monBlan = monBlan + climbers;
    } else if (climbers >= 13 && climbers <= 25) {
        kilimanjaro = kilimanjaro + climbers;
    } else if (climbers >= 26 && climbers <= 40) {
        k2 = k2 + climbers;
    } else {
        everest = everest + climbers;
    }
}


let musalaPercent = musala / totalPeople * 100;
let monBlanPercent = monBlan / totalPeople * 100;
let kilimanjaroPercent = kilimanjaro / totalPeople * 100;
let k2Percent = k2 / totalPeople * 100;
let everestPercent = everest / totalPeople * 100;

console.log(`${musalaPercent.toFixed(2)}%`);
console.log(`${monBlanPercent.toFixed(2)}%`);
console.log(`${kilimanjaroPercent.toFixed(2)}%`);
console.log(`${k2Percent.toFixed(2)}%`);
console.log(`${everestPercent.toFixed(2)}%`);

}
