The InAppPurchase Plugin in Cordova is throwing the error message "Encountered an error: Cannot access the 'getProducts' property as it is undefined."

Currently, I am utilizing the cordova in-app-purchase plugin for my application. However, I am encountering an error that reads "ERROR TypeError: Cannot read property 'getProducts' of undefined"

The .ts file appears as follows:

window['plugins'].inAppPurchase.getProducts(productIds).then(products => {
      console.log('got products: ', JSON.stringify(products));
      self.buyProducts(products[0].productId);

    });

I am stuck at this point and would greatly appreciate any assistance. Thank you in advance.

Answer №1

You may want to reconsider how you are utilizing the inAppPurchase class object. Here is a suggested approach to get it working correctly.
To incorporate the plugin, execute the following command:

cordova plugin add cordova-plugin-inapppurchase

Once the plugin is successfully installed and configured, import and utilize it in the necessary component as shown below.

import { InAppPurchase } from '@ionic-native/in-app-purchase/ngx';

and then inject it into the constructor like this 

constructor(
    private iap: InAppPurchase,
  ) {
        this.iap
        .getProducts(PaymentPage.PRODUCT_IDS)
        .then((products) => {
          console.log('Received products', JSON.stringify(products));                            
         })
        .catch((err) => {
          console.log(JSON.stringify(err));          
        });
}

This should help address your issue.
