# Troubleshooting

> Common issues and solutions for the Cognite DB extractor.

## The extractor is receiving 401 errors from CDF

HTTP error 401 means that the service did not recognize the authentication the client provided. If the Cognite API returns 401 errors to the extractor, the extractor successfully obtained an authentication token, but the token is not valid for the project in question.

If this happens, the configured `project` or `host` in the `cognite` section is usually incorrect.

## The extractor is not setting the data set when using remote configuration

If you set up the extractor to run with remote configuration, only the `host`, `project`, `idp-authentication`, and `extraction-pipeline` fields in the `cognite` section are read from the file on the local machine. Other fields in the `cognite` section, such as `data-set`, must be added to the configuration file in the extraction pipelines.
