Issue with Uploading Image Using fileManager in Google Generative AI API

Gemini API

Hello Google Community,

I’m currently working on a project that involves integrating image file uploads into a chatbot using the Google Generative AI API. I’ve encountered a problem with the image upload functionality and would appreciate any guidance or suggestions.

I am trying to use the fileManager from the Google Generative AI SDK to upload an image file, but I’m encountering issues.

const uploadedFile = await fileManager.uploadFile(userImage.filepath, userImage.mimetype);
fileUri = uploadedFile.uri;

The error I’m encountering

TypeError: _google_generative_ai__WEBPACK_IMPORTED_MODULE_0__.GoogleAIFileManager is not a constructor

Steps taken

  1. Importing fileManager: I attempted to import GoogleAIFileManager from @google/generative-ai but received the error mentioned above.
  2. Code Implementation: The code for uploading the image is as follows:
import { GoogleGenerativeAI } from "@google/generative-ai";

// API key for accessing Google Gemini API
const apiKey = process.env.API_KEY;

const genAI = new GoogleGenerativeAI(apiKey);
const fileManager = new GoogleAIFileManager(apiKey);  // Error occurs here
  1. Workaround: I’ve used the axios package to manually upload the file, which should work correctly. Here’s the code snippet:
const axios = require('axios');
const fs = require('fs');
const FormData = require('form-data');

async function uploadToGemini(filePath, mimeType) {
    const form = new FormData();
    form.append('file', fs.createReadStream(filePath), { contentType: mimeType });
    
    const response = await axios.post('https://api.generativeai.googleapis.com/v1beta3/files:upload', form, {
        headers: {
            ...form.getHeaders(),
            'Authorization': `Bearer YOUR_API_KEY`,
        }
    });

    return response.data;
}

Questions:

  1. Correct Usage: Is GoogleAIFileManager the correct way to handle file uploads, or is there an alternative approach I should use?
  2. API Endpoint: Could there be a discrepancy with the API endpoint for file uploads? The URL https://api.generativeai.googleapis.com/v1beta3/files:upload is being used, but should it be different?
  3. Authentication Issues: Are there any authentication or permissions issues that might be affecting the usage of fileManager?

Any insights or suggestions would be highly appreciated as I work to resolve this issue.
