TypeError: chargebee.subscription.list is not a function

Question

When I'm trying to make request with Chargebee I'm getting an error

TypeError: this.chargebee.subscription.list is not a function

But it's defined when I'm trying to debug it:

This is function where I'm making the request:

 async test(){
    return new Promise((resolve, reject) => {
      this.chargebee.subscription.list({
        limit: 2,
        "plan_id[in]": ["basic", "no_trial"]
      }).request(function (error, result) {
        if (error) {
          //handle error
          console.log(error);
        } else {
          resolve(result)
          for (var i = 0; i < result.list.length; i++) {
            var entry = result.list[i]
            console.log(entry);
            var subscription = entry.subscription;
            var customer = entry.customer;
            var card = entry.card;
          }
        }
      });
    })
  }

Why we have error that function is undefined, when it is defined? Appreciate any help, Thanks!

Why we have error that function is undefined, when it is defined?

Your error isn't that the function is undefined, it's that this.chargebee.subscription.list is not a function. Indeed, take a look at your debugging output: list = Object {request: } - it's an object, not a function, yet you're trying to call it as a function: this.chargebee.subscription.list(...).request(...)
