I need help to upload file (Image) through Cloud Function. (Node js)

I need help to upload file (Image) through Cloud Function. Now i receive an error message, ""error": "Cannot read properties of undefined (reading 'Symbol(Symbol.asyncIterator)')" with base64 technique.

my code is: // Decode the base64-encoded image const base64Data = profilePicture.replace(/^data:image/\w+;base64,/, ""); const buffer = Buffer.from(base64Data, 'base64');

// Save the decoded image as a file const filePath = path.join('/tmp', ${ID.unique()}.png); fs.writeFileSync(filePath, buffer); const fileStream = fs.createReadStream(filePath);

//Save file to storage const uploadedFile = await storage.createFile(teacherImageBucketId, ID.unique(), fileStream);
