This error code is reported when the location service is unavailable and relevant APIs cannot be called.
**Possible Causes**
1. The location service fails to be started. As a result, the communication between the application and the location service fails, and the location service is unavailable.
2. The GNSS chip fails to be initialized, and thus the GNSS positioning function becomes invalid.
3. The network positioning service is abnormal, and thus the network positioning function becomes invalid.
**Solution**
Stop calling the API.
