Download file from firebase and upload to stripe for id verification - node.js

Question

Im trying to get a id jpeg that i have stored in firebase storage and upload it to stripe in order to allow my customers to verify their identity. However i get several errors and the function stops
import * as https from 'https'
import * as fs from 'fs'
const stripe = Stripe('sk_test');
function getidFile(url: string):Promise<any>{
return new Promise((resolve,reject) => {
const file = fs.createWriteStream("test.jpg");
https.get(
url,
function(response: IncomingMessage){
console.log('Response ', response);
response.pipe(file);
file.on('finish', function() {
file.close();
resolve(file);
});
}
).on('error', function(err) { // Handle errors
reject(err);
});
});
}
function uploadFileToStripe(fileUrl:string,fileType:string,fileName:string):Promise<any>{
return getidFile(
fileUrl
).then(
(data:any) => {
console.log('File as blob ', data);
const upload: Promise<any> =
stripe.files.create(
{
file: {
data: data,
name: fileName,
type: 'image/jpeg',
},
purpose: 'identity_document',
}
);
return upload.then(
(document: any) => {
console.log('Document upload ', document);
return document;
}
).catch(
(_error: any) => {
console.log('Error uploading document ', _error);
return _error;
}
)
}
).catch(
(_error:any) => {
console.log('Error with response ', _error);
return _error;
}
);
}
Error: EROFS: read-only file system, open 'test.jpg'
and then my function stops.

I don't use URL. Use admin.storage() to access your file.
export const uploadFileToStripe = functions.https.onCall(async(data,context)=>{
const bucket = admin.storage().bucket('xyz.appspot.com');
const path = require('path');
const os = require('os');
const fs = require('fs');
const fileName = data['fileName'];
const tempFilePath = path.join(os.tmpdir(), fileName);
await bucket.file(fileName).download({destination:tempFilePath});
console.log('File created at', tempFilePath);
return await stripe.files.create({
purpose: 'identity_document',
file: {
data: fs.readFileSync(tempFilePath),
name: 'fileUploadDoc.png',
type: 'application/octet-stream',
},
});
});
