couldn't get inputSeparator working i.e.

import path from 'node:path';
import nconf from 'nconf';

// config
process.env['PATHS__LOGDIR'] = 'test';

nconf.argv({parseValues: true})
.env({lowerCase: true,
// inputSeparator : '', doesnt work
separator : '', // works ok
parseValues: true});
// .file({ file: 'config/server.json' });

const logFile = path.join(nconf.get('paths:logdir'), 'server.log');
console.log('directory ', nconf.get('paths:logdir'));
console.log('logFile ', logFile);
console.log('should be ', process.env.PATHS__LOGDIR);
