Cannot convert undefined or null to object at Function.entries (<anonymous>)

I’m trying to pull data from the console on one page, written in json and then transfer it to another using this script, but I’m having problems.
Help solve the problem)

JS code

chosen = JSON.parse(sessionStorage.getItem('chosen'))
console.log(chosen)
let s = "";
let sum = 0.0;

for (let [key, value] of Object.entries(chosen)) {
    s += `<p>${key} (${value['value']}): \u20ac ${value['price']}</p>`
    sum += parseFloat(value['price'])
}
s += `<p>Total: ${sum}</p>`

document.getElementById("components").innerHTML += s;

Error

order.js:6 Uncaught TypeError: Cannot convert undefined or null to object
    at Function.entries (<anonymous>)

>Solution :

Can you define your chosen variable correctly and try again?

This chosen = JSON.parse(sessionStorage.getItem('chosen')) should be like this => const chosen = JSON.parse(sessionStorage.getItem('chosen'))
