Here is a test exemple:

You can try using the msg.secureOptions and set the ca to the cert present by the ftp server.
I dont't now how this work, but here it is mentioned that it can be a string

msg.secureOptions = {
   ca: <<PEM String>>)
};

Here is the init of the tls connection of the node-ftp package:
