Hey @Gokula Krishna,

Can you confirm your product identifier in your StoreKit config file matches what you entered in the RevenueCat dashboard? This typically means there’s some type of configuration error and our SDK can find the products. Additionally, I’d recommend taking a look at our docs for testing StoreKit purchases: https://docs.revenuecat.com/docs/apple-app-store#ios-14-only-testing-on-the-simulator

Our Empty Offerings guide details the rest of the common problems with this type of error, too: https://rev.cat/why-are-offerings-empty

@cody 

Here are the entire steps I have performed

1/ Create a new StoreKit config

2/ Manage schemes

3/ Duplicate my Runner

4/ Finish duplicating

5/ Assign StoreKit config

6/ Add my products

7/ Add my products on XCode

8/ Save the Public cert

9/ Upload to test

10/ Signed agreements

11/ My bundle ID in XCode

12/ My bundle ID in RC

13/ My Bundle ID in AppStore

I use the latest version of the dev tools and simulators.

Still it doesn’t work.

Kindly help

Hey @Gokula Krishna,

Thanks for the detailed information, it certainly seems like you have things set up correctly. Can you send over full debug logs recreating this error (from app launch)? Are you able to try on a device and see if it works there?

@cody 

This is all the logs I have

Notes:

1. I run my setup on https://www.macincloud.com/
2. I test it on simulator

@cody

Can you help me check the above issue?

@Gokula Krishna A couple of things to check here, although at first glance the setup seems correct: 

• Could you make sure that the API key is correct? 
• Ensure that the Configuration file is included in the target, by selecting it and then in the sidebar on the right, checking that it’s included in Target membership
• Anything else in the debug logs that might shed some light? I.e.: other warnings that might at first glance seem unrelated? 

@Andy 

• API key is correct I checked multiple times
• Yes the configuration is correct

• I can’t see any other errors apart from the above logs

@Andy 

I found it. There was a configuration error on storekit product IDs.

Thank you for the support.

I’m glad you found it! Let us know if you run into anything else. 

Have a great day!
