I'm trying to convert specific images saved to Firebase storage as webp.

I'm able to download the image to the function instance

import * as functions from "firebase-functions";
import * as admin from "firebase-admin";
import * as os from "os";
import * as path from "path";

admin.initializeApp();

const sharp = require("sharp");
const storage = admin.storage();

const bucket = storage.bucket();
const imageRef = data.storageRef;
const fileName = path.basename(imageRef);
const webpFileName = `$fileName.split(".").shift().webp`;
try 
 console.log("Downloading file");
 const tempFilePath = path.join(os.tmpdir(), fileName);
 const imageBuffer = await bucket.file(imageRef).download(destination: tempFilePath);
 console.log(`Downloaded file to $tempFilePath`);

 // save image as webp
 const webpFile = sharp(imageBuffer).toFile(webpFileName);
 console.log("Sharpening");
 const webpRef = await bucket.upload(webpFile);
 console.log(`Uploaded $webpRef`);
 return imageRef;
 catch (e) 
 console.log(`Error $e.message`);
 return null;
 

I'm able to download the image but sharp is throwing an Unsupported input object error

Any suggestions? Thanks :)
