Found the issue it is because of setting exchange.options overwrites all the normal options.

@bigcountry-scav you’re right, thx for your help! To fix it change your code like so:

  exchange = new exchangeClass({
      "apiKey": apiKey,
      "secret": secret,
      "enableRateLimit": true,
      "verbose": true,
      "options": {
          'defaultType': 'future',
      }
  });

or like so:

  exchange = new exchangeClass({
      "apiKey": apiKey,
      "secret": secret,
      "enableRateLimit": true,
      "verbose": true
  });

  exchange.options['defaultType'] = 'future'

Let me know if that does not resolve the issue.
