I would really appreciate some help here. I have a script with these functions:

function getOAuthService() {
  return OAuth2.createService('Basecamp')
    .setAuthorizationBaseUrl('https://launchpad.37signals.com/authorization/new')
    .setTokenUrl('https://launchpad.37signals.com/authorization/token')
    .setClientId('client_id')
    .setClientSecret('secret')
    .setCallbackFunction('authCallback')
    .setPropertyStore(PropertiesService.getUserProperties())
    .setScope('read')
    .setParam('type', 'web_server')
    .setRedirectUri('https://script.google.com/macros/d/SCRIPT_ID/usercallback');
}

function authorize() {
  var basecampService = getOAuthService();
  if (!basecampService.hasAccess()) {
    var authorizationUrl = basecampService.getAuthorizationUrl();
    Logger.log('Open the following URL and re-run the script: ' + authorizationUrl);
  } else {
    Logger.log('You are already authorized.');
  }
}

The client_id, secret and script_id are actual ids and are legit. When I run the authorize() function I get the URL and open it and it takes me to the page where I can allow access and authorize. However, when I do, I just get this message:

Error: Error retrieving token: Unsupported type. Expected “web_server” or “refresh”. (line 605, file “Service”)

I have no idea why and can’t find a fix. Any ideas? Thanks!

I can’t really try a lot myself since I’m not a developer, just trying to do this to automate some stuff
