Node.JS API and CITY code is wrong and api key is wrong

hi, i have problem when i type variable in ${ } i getting error because its wrong api.key and its NOT ! when i type it directly to get method it works perfect

const https = require("https");
const api = require("./api.json");

function get(query) {
    const request = https.get('https://api.openweathermap.org/data/2.5/weather?zip=${query}&appid=${api.key}', (response) => {
        let body = "";
        response.on("data", chunk => {
            body += chunk;
        });
        response.on("end", () => {
            console.log(body);
        });
});
}

{
  "key" : "385a38ead92aa38a3e4e857ec3323062"
}

For template literals to work, in the request declaration, you need to replace those single quotes with back ticks. 

//Current
const request = https.get('https://api.openweathermap.org/data/2.5/weather?zip=${query}&appid=${api.key}', 

//New
const request = https.get(`https://api.openweathermap.org/data/2.5/weather?zip=${query}&appid=${api.key}`,

Is api.json in the same directory as the js file you are calling it from? I ask because the ./ in const api = require("./api.json"); means to use the current directory. Please check that this is not a path issue, meaning the file could not be found.

You could try a console.log(api.key); after declaring the api variable to ensure the api key is accessed correctly.

What is the value of query if you console.log it? Perhaps this is where the issue lies.

Interesting log is writed before CODE : 

const weather = require("./weather");
const query = process.argv.slice(2).join("_").replace(" ", "_");

weather.get(query);
console.log("LOG:" + query);
