Authentication Problems

Authentication troubleshooting — 401 errors, invalid keys, missing configuration.

This guide covers common authentication-related issues when using the LayerLens Python SDK.

Common Authentication Errors

Invalid or Missing API Key

Error: AuthenticationError: Invalid API key

Symptoms:

• 401 Unauthorized responses
• "Invalid API key" error messages
• Authentication fails immediately

Missing Required Configuration

Error: StratixError: The api_key client option must be set either by passing api_key to the client or by setting the LAYERLENS_STRATIX_API_KEY environment variable

Set the environment variable or pass the key explicitly:

export LAYERLENS_STRATIX_API_KEY="your-api-key"

from layerlens import Stratix

client = Stratix(api_key="your-api-key")
