Javascript – TypeError: functions.storage.object is not a function with firebase

I am trying to use Firebase Functions to listen for file upload events in Cloud Storage, but I encountered an error during deployment that says:

functions.storage.object is not a function.

    const functions = require("firebase-functions");

    exports.processFile = functions.storage.object().onFinalize(async (object) => {try {console.log("File uploaded:", object.name);

    if (!object.name) {
      console.log("No file name found.");
      return null;
    }

    console.log(`File content type: ${object.contentType}`);
    return null;
    } catch (error) {console.error("Error processing file:", error);return null;}});

version
"firebase-admin": "^11.8.0",
"firebase-functions": "^4.3.1",
"node": "16"

I follow all instruction and also asked chatgpt. I think everything is right.but I cannot deplot it to the cloud. Hope someone can help me!

    You are using the 1st gen cloud functions, therefore update the required module to the following:

    const functions = require('firebase-functions/v1');

    Then calling onFinalize() should work. Check the documentation here:

    https://firebase.google.com/docs/functions/gcp-storage-events?gen=1st

    You should start with the examples in the documentation. The SDKs and APIs have changed. The version 2 API is now the default. Your import should look like this:

     const {onObjectFinalized} = require("firebase-functions/v2/storage");

    And your function declaration should look like this:

    exports.processFile = onObjectFinalized(async (event) => {
// ...
});

    Also note that your modules are very old versions. Use the latest firebase-functions 6.2.0 and firebase-admin 13.0.2. You should also consider upgrading the target node version since 16 is also very old and will no longer be supported in the future.
