Google Cloud Storage unexpected identifier "storage" - google-cloud-storage

Question

I found this documentation and this documentation about uploading files to Google Cloud Storage. I wrote this code:
const {Storage} = require('#google-cloud/storage')();
const projectId = 'myapp-cd94d';
const storage = new Storage({
projectId: projectId,
});
const bucketName = "myapp-cd94d.appspot.com";
const filename = { 'test': 'file'};
var serviceAccount = require("./serviceAccountKey.json")
admin.initializeApp({
credential: admin.credential.cert(serviceAccount),
storageBucket: "myapp-cd94d.appspot.com"
});
var bucket = admin.storage().bucket();
await storage.bucket(bucketName).upload(filename, {
gzip: true,
metadata: {
cacheControl: 'no-cache',
},
});
console.log(`${filename} uploaded to ${bucketName}.`);
I tried to deploy the code and got this error message:
await storage.bucket(bucketName).upload(filename, {
^^^^^^^
SyntaxError: Unexpected identifier
Is there something wrong with my first line
const {Storage} = require('#google-cloud/storage')();
Why are there curly brackets around Storage? Am I supposed to replace {Storage} with something else?

Why are there curly brackets around Storage? Am I supposed to replace {Storage} with something else?
The curly braces around Storage indicate a deconstructing assignment. It allows you to extract multiple values from data stored in objects and Arrays. The example import from the documentation you shared (const {Storage} = require('#google-cloud/storage');) is correct.
The error message SyntaxError: Unexpected identifier is not saying that it didn't identify storage, it's saying that it didn't expect storage to be there. The error is due to await.
await can only be used in an async function. For example:
async function myAsyncFunction() {
let result = await lengthyFunction();
console.log(result);
}
myAsyncFunction();
Try wrapping the bucket upload call inside an async function to avoid the error when using await.
