Authentication error while implementing Stripe in Node js

Question

I am trying to implement Stripe in my backend which is in node js. While calling it from front end I am getting this error:

You did not provide an API key, though you did set your Authorization header to "null". Using Bearer auth, your Authorization header should look something like 'Authorization: Bearer YOUR_SECRET_KEY'. See https://stripe.com/docs/api#authentication for details, or we can help at https://support.stripe.com/.

Here is my code:

const stripe = require("stripe")(process.env.keySecret);

if(req.body.type == 'stripe') {
        const token = req.body.token;
        const amount = req.body.amount;
        let charge = stripe.charges.create({
            amount: amount,
            source: token,
            currency: 'USD'
        },(err, chargeData) => {
            if(err) {
              console.log('error in buy premium api error... ', err);
              return;
            }
            let payment = [];
            payment.push({
              amount: chargeData.amount,
              address: chargeData.billing_details.address,
              email: chargeData.billing_details.email,
              payment_method_details: chargeData.payment_method_details.card
            })
            console.log('charge... ', charge);
            if(charge) {
              register.findByIdAndUpdate({ _id: therapist._id }, 
                {
                  $set:
                  {
                    payment_details: payment
                  }
                }, {new:true}, (e1, updatedUser) => {
                if(e1) {
                  return;
                }
  
                resolve(updatedUser);
              })
            }
        })
      }
      else {
        let err = 'No payment type define..';
        return reject(err);
      }

My req.body is:

{
"token": "tok_1F2XPBG04BYg8nGtLoWnQwRU", // coming from front end
"amount": "250",
"type":"stripe" 
}

The secret key is test secret key which is like sk_test_xxxxxxxxxxxxxxxx.

My front end is in Angular 6 and from front end I am passing my test publishable key i.e. pk_test_xxxxxxxxxxxxxxxxx. I am passing proper data to the both front end as well as backend. Where am I mistaken?

Since you are calling .env file, you have to include the following line before requiring stripe:

require ("dotenv").config();
const stripe = require("stripe")(process.env.keySecret);
