Google Play error getting SKU details

I am using Ionic3 with Ionic Native In App Purchase . I have installed multiple in-app purchases on the Google Play Store.

It worked fine and I could view all products with:

.getProducts(this.PRODUCT_IDS)

until I add a test user. Now I am getting this error:

Error retrieving SKU information

after i tried to make a purchase from a tested user.

this.iap.buy(item.productId).then((data) => {
  return this.iap.consume(data.productType, data.receipt, data.signature);
}).then(() => {
  console.log('product was successfully consumed!');

      

        
        
        
      

    

And now I can no longer access the products.

I read here that the reason may be that testers are unable to use the product and suggest this solution:

SOLUTION: Pull "orders" to the Play Console and "cancel" the pending purchase.

However, I have two questions:

• How do you validate purchases if the tester is unable to use the product?
• Where do you pull up orders on the Play Console? I am looking at "Order Management" but no orders listed.
