# SDK troubleshooting

SDK-specific troubleshooting.

See [Python SDK troubleshooting](https://github.com/LayerLens/gitbook-full/blob/main/13-reference/sdk-python/troubleshooting.md) for the full list. Common ones:

* `AuthenticationError` — wrong env var name (`LAYERLENS_STRATIX_API_KEY`)
* `RateLimitError` — usually transient; SDK retries
* `NotFoundError` — wrong ID or wrong org
* SSL — corporate proxy; configure CA bundle
