Error messages are not useful
The error message conversion from nethsm-sdk-rs is somewhat terrible.
When the API e.g. returns a 403 (due to wrong user used for the call) when calling the restore endpoint, the error message is entirely gibberish: error: nethsm::Error - NetHSM API error: Restoring backup failed: error in serde: EOF while parsing a value at line 1 column 0
