InAppPurchase Invalid Product Identifiers - Possible Causes

It was a long night chasing a problem in my in-app purchase trials, but I can't solve this problem. My product id keeps returning as "invalid product id". Hope someone points out this; (I have push notifications with the current initialization profile and appId)

1. My app id generated (no wildcards) - inApp purchase enabled

2. My IAP (in-app purchase) has been added to the "In-app purchase management" section and has been cleared for sale.

3. My IAP was added 24 hours ago (maybe a couple more hours) and is in the "Waiting for viewing" state.

4. My application itself is rejected by the developer> and in the "ready to download" state, a purchase from the application has been added to the application.

5. My phone is not jailbroken (at least it no longer worked anyway)

6. I work with 3GS, iOS 5.1.

7. My current provisioning profile is a Developer Profile, not a Distribution Profile. The "distribution profile" is used only when downloading the application binary.

8. I'm going for iOS 5.0, and the build configuration is set to Debug.

9. I literally uninstalled the application 100 times.

10. All details are installed in iTunes Connect, including bank details.

11. I created a test user and went into "Settings> Store" on my device.

12. My SKProductRequest:

    SKProductsRequest *productRequest = [[SKProductsRequest alloc]initWithProductIdentifiers:[NSSet setWithObject:@"com.my_site.my_app.my_product"]];
