Occasional crash when attempting to in-app purchase on Android device

App is frequently terminated with a NullPointerException when attempt to request in-app purchase.
It is assumed that product information cannot be retrieved if there is no Google account logged in to the Android phone.

It hasn't been happening since I added the null check to the two lines of code below.
Please check if it is the correct correction.

Engine\Plugins\Online\Android\OnlineSubsystemGooglePlay\Source\Java\BillingApiV2\com\epicgames\ue4\GooglePlayStoreHelper.java

Line 177 :
if (response == BillingClient.BillingResponseCode.OK && skuDetailsList != null)

Line 277:
if(response == BillingClient.BillingResponseCode.OK && skuDetailsList != null)
