I have added two firebase functions to my flutter app to implement Stripe.
const functions = require("firebase-functions");
const stripe = require("stripe")(functions.config().stripe.testKey)
const calculateOrderAmount = (items) => {
prices = [];
catalog = [
{ 'id': '0', 'price': 3.99, },
{ 'id': '1', 'price': 7.99, },
{ 'id': '2', 'price': 9.99, },
];
items.array.forEach(item => {
price = catalog.find(x => x.id == item.id).price;
prices.push(price);
});
return parseInt(prices.reduce((a, b) => a + b) * 100);
}
const generateResponse = function (intent) {
switch (intent.status) {
case 'requires_action':
return {
clientSecret: intent.clientSecret,
requiresAction: true,
status: intent.status,
}
case 'requires_payment_method':
return {
'error': 'Your card was denied, please provide a new payment method',
};
case 'succeded':
console.log('Payment succeded')
return {
clientSecret: intent.clientSecret,
status: intent.status,
};
}
return {
error: 'Failed'
};
}
exports.StripePayEndpointMethodId = functions.https.onRequest(async (req, res) => {
const { paymentMethodId, items, curency: currency, useStripeSdk, } = req.body;
const orderAmount = calculateOrderAmount(items);
try {
if (paymentMethodId) {
const params = {
amount: orderAmount,
confirm: true,
confirmation_method: 'manual',
currency: currency,
payment_method: paymentMethodId,
use_stripe_sdk: useStripeSdk,
}
const intent = await stripe.paymentIntents.create(params);
console.log('Intent: ${intent}');
return res.send(generateResponse(intent));
}
res.sendStatus(400)
} catch (error) {
return res.send({ error: error.message });
}
});
exports.StripePayEndpointIntentId = functions.https.onRequest(async (req, res) => {
const { paymentIntentId } = req.body;
try {
if (paymentIntentId) {
const intent = await stripe.paymentIntents.confirm(paymentIntentId);
return res.send(generateResponse(intent));
}
return res.sendStatus(400)
} catch (error) {
return res.send({ error: error.message })
}
});
However when I run the command firebase deploy --only functions it shows me an error. Here is the full log:

Functions deploy had errors with the following functions:
StripePayEndpointIntentId(us-central1)
StripePayEndpointMethodId(us-central1)
i functions: cleaning up build files...
⚠ functions: Unhandled error cleaning up build images. This could result in a small monthly bill if not corrected. You can attempt to delete these images by redeploying or you can delete them manually at https://console.cloud.google.com/gcr/images/jimv01/us/gcf
Error: There was an error deploying functions:
- Error Failed to update function StripePayEndpointMethodId in region us-central1
- Error Failed to update function StripePayEndpointIntentId in region us-central1
Here is also the package.json file:

"eslint-config-google": "^0.14.0",
"firebase-functions-test": "^3.1.0"
},
"private": true
}
From the log, I assume that the problem is that it can’t find the stripe module and, as you can see, the stripe dependency doesn’t show even though I added it through the command npm install stripe --save. For this reason, I tried adding it manually:
"dependencies": {
"firebase-admin": "^11.8.0",
"firebase-functions": "^4.3.1",
"stripe": "^6.28.0"
},
However, it shows another error:

Error: There was an error deploying functions:
- Error Failed to update function StripePayEndpointMethodId in region us-central1
- Error Failed to update function StripePayEndpointIntentId in region us-central1
Then, I discarded the option of manually adding the stripe module. Moreover, when I faced the first issue, the functions were loaded on firebase but with an error, so they are there but I can’t use them.
