Development

# Install dependencies
npm install

# Build the node
npm run build

# Run linting
npm run lint

# Fix linting issues
npm run lintfix

# Format code
npm run format

API Testing

A test script is included to verify API connectivity:

node test-api.js

Note: Update the API key in test-api.js with your actual WXAI API key before testing.

Expected Response Format

The WXAI API returns responses in Server-Sent Events (SSE) format. The node automatically handles this format and extracts the JSON data for use in n8n workflows.

Troubleshooting

⚠️ Important: Credential Validation Limitation

Known Issue: The credential test in n8n may show "success" even with invalid API keys due to WXAI API's response format (returns HTTP 200 with error details in the response body).

To properly validate your API key:

# Use the included test script
node test-credential-validation.js

# Or test manually
curl -X POST https://cs.rhwx-ai.com/api/ai/v1/chat/completions \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"gemini-2.0-flash","messages":[{"role":"user","content":"test"}],"max_tokens":1,"stream":false}'

Valid response: Contains choices array Invalid response: Contains {"code": 500, "message": "..."}

API Key Issues

• Ensure your API key is valid and active
• Check that the base URL is correct: https://cs.rhwx-ai.com/api/ai/v1
• Verify your account has sufficient credits/quota
• Use the test script to validate your API key before use

Model Issues

• The default model is gemini-2.0-flash
• Ensure the model is available in your WXAI account
