When running this example:
https://www.chargebee.com/checkout-portal-docs/eu-vat-validation-function.html#integration

 let cbInstance = Chargebee.getInstance();
  charegbeeInstance.load('functions').then(() => {
    const payload = {
          country: "DE",
          vat_number: "811569869",
        }
    cbInstance.vat.validateVat(payload).then(data => {
      // Your code here
    }).catch(err => {
      // Your code here
    })
  });

I'm always getting {status: undefined} as result.

Playground as example https://jsfiddle.net/r27panuv/

as the api states that
subscriptionId String Required if the sectionType involves a subscription related action

same goes for PortalForwardOptions->params -> subscriptionId / paymentSourceId

api

I know this package was just updated but I am still seeing some definitions which don't match the Chargebee.js API docs.

For example, in the docs Chargebee.init shows publishableKey as an optional field and several other properties such as enableRedirectMode and domain are included. Also, Chargebee.getPortalSections and Chargebee.registerAgain are not defined in this package.

Thank you for the work you've already done and I look forward to using this package when it is complete.

since it is not expected to provide every single callback if we dont need it
