Firebase Functions error when calling Stripe

I'm an iOS developer with very little experience in both Javascript and server code so I'm a little lost here.

I'm getting an error when I create a new user in firebase and trigger a function to create a new user in stripe. Here is my firebase function straight from Stripe's docs.

exports.createStripeCustomer = functions.auth.user().onCreate(async (user) => { 
    const customer = await stripe.customers.create({email: user.email});
    return admin.firestore().collection('stripe_customers').doc(user.uid).set({customer_id: customerId});
  });

I successfully create a new user in Stripe with a customer ID. enter image description here I get is this error in my firebase logs and don't capture the customer ID so I can save it in firestore. I'm not sure what I'm doing wrong or how to interpret this message. Any pointers would be greatly appreciated.

createStripeCustomer
ReferenceError: customerId is not defined at exports.createStripeCustomer.functions.auth.user.onCreate (/srv/index.js:120:93) at <anonymous> at process._tickDomainCallback (internal/process/next_tick.js:229:7)

I have also tried this return changing customerId to ID

return admin.firestore().collection('stripe_customers').doc(user.uid).set({customer_id: ID});

Here is where I finally ended up. I used a promise instead of await.

exports.createStripeCustomer = functions.auth.user().onCreate(async (user) => { 
  const stripePromise = new Promise((resolve, reject) => {
    stripe.customers.create({
      email: user.email
    }, (err, customer) => {
      if (err) {
        reject(err)
      } else {
        resolve(customer);
          stripePromise
            .then(customer => {
              return admin.firestore()
                .collection('stripe_customers')
                .doc(user.uid)
                .set({customer_id: customer.id});
            })
            .catch(error => { 
              console.log(`error resolving promise ${error}`)
            })
      }
    });
  })
});

It looks like, from the documentation, that the response object contains an id property. Perhaps you meant to write this line instead:

return admin.firestore()
    .collection('stripe_customers')
    .doc(user.uid)
    .set({customer_id: customer.id});  // use the ID property here
