% DATABASE_TO_JSON_ERROR Internal logic error: uknown %1 element found in state: %2
This error message is printed when conversion to JSON of the internal state is requested,
but the connection string contains unrecognized parameter. This is a programming error.
The software will continue operation, but the returned JSON data will be syntactically
valid, but incomplete. The unknown parameter will not be converted.
