[azamsolix]

var SMB2 = require('@marsaud/smb2');
async function m1() {
  // create an SMB2 instance
  var smb2Client = new SMB2({
    share: '***',
        domain: '***',
        username: '**',
        password: '*****',
        autoCloseTimeout:0
  });
  // console.log(smb2Client)
  let ans = await smb2Client;
  console.log('aa',ans)
 smb2Client.readFile('share-apis.txt', function(err, content) {
  if (err) throw err;
  console.log(content.toString());
});
}
m1()  ;

I am getting smbclient object in which connected property is returning false,However,I am able to use smb2client to read file
