openclaw - 💡(How to fix) Fix Gemini embedding provider: API key not loaded from .env (400 API_KEY_INVALID) [3 comments, 3 participants]

gemini embeddings failed: 400 {"error":{"code":400,"message":"API Key not found. Please pass a valid API key.","status":"INVALID_ARGUMENT","details":[{"@type":"type.googleapis.com/google.rpc.ErrorInfo","reason":"API_KEY_INVALID"}]}} 5. ❌ None of these work — same 400 error

Fix Plan

To resolve the issue, we need to ensure that the GEMINI_API_KEY environment variable is properly loaded and accessible to the Gemini embedding provider.

Here are the steps:

• Verify that the loadDotEnv() function is correctly loading the environment variables from ~/.openclaw/.env.
• Check if the GEMINI_API_KEY variable is being overridden or unset somewhere in the code.
• Ensure that the PROVIDER_PREFIX_OVERRIDES configuration is correctly set up to map the google provider to the GEMINI_API_KEY environment variable.

Example code to verify the environment variables:

console.log(process.env.GEMINI_API_KEY);
console.log(process.env.GOOGLE_API_KEY);

If the variables are not being loaded, you can try loading them manually using the dotenv package:

const dotenv = require('dotenv');
dotenv.config({ path: '~/.openclaw/.env' });

Alternatively, you can try setting the environment variables directly in the systemd service file:

Environment=GEMINI_API_KEY=<valid key starting with AQ.>
Environment=GOOGLE_API_KEY=<same key>

Verification

To verify that the fix worked, you can try running the Gemini embedding provider again and check if it uses the correct API key. You can also add logging statements to the code to verify that the environment variables are being loaded correctly.

Example code to verify the API key:

const apiKey = process.env.GEMINI_API_KEY || process.env.GOOGLE_API_KEY;
console.log(`Using API key: ${apiKey}`);

Extra Tips

• Make sure to restart the systemd service after updating the environment variables or configuration files.
• Verify that the ~/.openclaw/.env file has the correct permissions and ownership.
• Consider adding error handling to the code to handle cases where the API key is not found or invalid.
