Hello guys seem to have an issue with calling my tuned model below is my code

const fs = require('fs').promises;
const path = require('path');
const { GoogleAuth } = require('google-auth-library');
const axios = require('axios');

async function run() {
    // Load the service account key JSON file
    const keyFile = await fs.readFile(path.join(__dirname, 'secret.json'), 'utf8');
    const keys = JSON.parse(keyFile);

    // Initialize GoogleAuth for OAuth 2.0
    const auth = new GoogleAuth({
        credentials: keys,
        scopes: ['https://www.googleapis.com/auth/generative-language']
    });

    const client = await auth.getClient();

    // Get the access token
    const accessToken = await client.getAccessToken();

    const generationConfig = {
        temperature: 0.9,
        topP: 1,
        maxOutputTokens: 8192,
    };

    const requestBody = {
        contents: [{
            role: 'user',
            parts: [{ text: 'input: ' }, { text: 'output: ' }]
        }],
        generationConfig,
    };

    try {
        const response = await axios.post(
            'https://generativelanguage.googleapis.com/v1beta/tunedModels/copy-of-plan-house-model-a5iltlw1z6df:generateContent',
            requestBody, {
                headers: {
                    'Authorization': `Bearer ${accessToken.token}`,
                    'Content-Type': 'application/json',
                }
            }
        );

        console.log('Generated content:', response.data.candidates[0].content.parts[0].text);
    } catch (error) {
        console.error('Error generating content:', error.response ? error.response.data : error.message);
    }
}

run();

i get error
Error generating content: {
error: {
code: 403,
message: ‘You do not have permission to access tuned model tunedModels/copy-of-plan-house-model-a5iltlw1z6df.’,
status: ‘PERMISSION_DENIED’
}
}

Your comment in the code indicates you’re using a service account.

How have you permitted the service account to the trained model?

3

  • Editor

  • Owner

  • Service Account Admin

4

For Service Account it’s usually enough if you have Owner permission without any other permission.

Have you made a successful request with your service account before because if am not wrong you need to pass the Project ID in the header as well.

5

can you show me an example code you use please in any language you used

6

So you’ve permitted the service account to the project, but not to the model?

That’s the problem, I think. The model maintains its own permission structure that permit it to a user.

So you’ll need to permit it (by its service account email address) to the model itself. Which require you to authenticate as yourself first to grant the permission. See herefor more info.
