Troubleshooting Guide: Missing or Incorrect API Keys in R2R

API keys are crucial for authenticating and accessing various services integrated with R2R. Missing or incorrect API keys can lead to connection failures and service disruptions. This guide will help you identify and resolve API key issues.

​
1. Identifying API Key Issues

Common symptoms of API key problems include:

  • Error messages mentioning “unauthorized,” “authentication failed,” or “invalid API key”
  • Specific services or integrations not working while others function correctly
  • Unexpected 401 or 403 HTTP status codes in logs

​
2. Checking API Key Configuration

​
2.1 Environment Variables

R2R uses environment variables to store API keys. Check if the required environment variables are set:

env | grep API_KEY

Look for variables like:

  • OPENAI_API_KEY
  • ANTHROPIC_API_KEY
  • AZURE_API_KEY
  • UNSTRUCTURED_API_KEY
  • HATCHET_CLIENT_TOKEN

​
2.2 Configuration Files

If you’re using configuration files (e.g., r2r.toml), verify that API keys are correctly set:

grep -i "api_key" /path/to/your/r2r.toml

​
3. Common API Key Issues and Solutions

​
3.1 OpenAI API Key

Issue: OpenAI services not working or returning authentication errors.

Solution:

  1. Verify the OPENAI_API_KEY is set: 
    echo $OPENAI_API_KEY
  2. Ensure the key starts with “sk-”.
  3. Check the key’s validity in the OpenAI dashboard.
  4. Regenerate the key if necessary and update the environment variable.

​
3.2 Anthropic API Key

Issue: Claude or other Anthropic models not functioning.

Solution:

  1. Confirm the ANTHROPIC_API_KEY is set: 
    echo $ANTHROPIC_API_KEY
  2. Verify the key format (typically starts with “sk-ant-”).
  3. Test the key using Anthropic’s API documentation.

​
3.3 Azure API Key

Issue: Azure-based services failing to authenticate.

Solution:

  1. Check the AZURE_API_KEY is set: 
    echo $AZURE_API_KEY
  2. Verify additional Azure-related variables:
    • AZURE_API_BASE
    • AZURE_API_VERSION
  3. Ensure the key and endpoint match your Azure resource configuration.

​
3.4 Unstructured API Key

Issue: File ingestion or parsing failures.

Solution:

  1. Verify the UNSTRUCTURED_API_KEY is set: 
    echo $UNSTRUCTURED_API_KEY
  2. Check if the Unstructured API URL is correctly configured: 
    echo $UNSTRUCTURED_API_URL
  3. Test the key using Unstructured’s API documentation.

​
3.5 Hatchet Client Token

Issue: Workflow orchestration failures or Hatchet connectivity issues.

Solution:

  1. Confirm the HATCHET_CLIENT_TOKEN is set: 
    echo $HATCHET_CLIENT_TOKEN
  2. Verify the token was correctly generated during the R2R setup process.
  3. Check Hatchet logs for any token-related errors.

​
4. Updating API Keys

If you need to update an API key:

  1. Stop the R2R service:

    docker-compose down

  2. Update the key in your environment or configuration file:

    export NEW_API_KEY="your-new-key-here"

    Or update the r2r.toml file if you’re using configuration files.

  3. Restart the R2R service:

    docker-compose up -d

​
5. Security Best Practices

  • Never commit API keys to version control.
  • Use environment variables or secure secret management solutions.
  • Regularly rotate API keys, especially if you suspect they’ve been compromised.
  • Use the principle of least privilege when creating API keys.

​
6. Debugging API Key Issues

If you’re still having trouble:

  1. Check R2R logs for detailed error messages:

    docker-compose logs r2r

  2. Verify network connectivity to the API endpoints.

  3. Ensure your account has the necessary permissions for the API keys you’re using.

  4. Try using the API key in a simple curl command to isolate R2R-specific issues:

    curl -H "Authorization: Bearer $YOUR_API_KEY" https://api.example.com/v1/test

​
7. Getting Help

If you’ve tried these steps and are still experiencing issues:

  1. Check the R2R documentation for any recent changes or known issues with API integrations.
  2. Search the R2R GitHub issues for similar problems and solutions.
  3. Reach out to the R2R community on Discord or other support channels, providing:
    • R2R version
    • Relevant logs (with sensitive information redacted)
    • Steps to reproduce the issue
    • Any error messages you’re seeing

Remember, never share your actual API keys when seeking help. Use placeholders or redacted versions in any logs or code snippets you share publicly.
