Hey @Panudech Changthong, just to make sure here: are the products that you have set up in your configuration file, also set up in the RevenueCat dashboard? 

The steps to do that are detailed here: https://docs.revenuecat.com/docs/entitlements#revenuecat-configuration

The products that you have in the storekit configuration file need to be set up in the RevenueCat dashboard, and the product identifiers need to match exactly so that they show up in offerings. In addition, you’ll have to set up packages and offerings (also described in the link above)

I am trying check again now

@Andy I sure i correct step your reference

I clear and create new information but can’t success

and this is my product on revenuecat 

below my offer

I thing i set correct but can’t fetch data

@Panudech Changthong could you share the debug logs? They might shed some light on what’s going on here

This is screen on debug @Andy  offering is null

@Panudech Changthong I think that might be because the line hasn’t executed yet? The object should be non-null when you move to the `print` line. 

Here’s how to get debug logs https://docs.revenuecat.com/docs/debugging. Could you attach them here?

@Andy

My debug log don’t show message i don’t understand why

According document just code below 

await Purchases.setDebugLogsEnabled(true);

await Purchases.setup(key,    appUserId: "my_app_user_id");

On my schema i unchecked OS_ACTIVITY_MODE

** Right now i dowgrade lib from 4.1.0 to 3.10.0

I’m not sure why you’re not seeing the debug logs, perhaps they don’t show up in that specific IDE? Have you tried seeing what is displayed when running from Xcode? 

@Andy 

I try get offering from api i can fetch data succuss 

Ok i finding solution to show message

@Andy 

I found cause miss log message 

because ios simulator don’t show bu android emu show message

I got debugging log below

@Panudech Changthong you should try running the iOS app directly from Xcode, I believe that’s the only way to get the logs from a Flutter app on iOS. 

Are you also having issues with the Android setup? Or does that one work as expected? 

@Andy 

OK i try run on IOS 

Android i will setup after ios finished

@Andy 

I run on IOS got message below 

I'm wondering why text my_app_user_id

I found my_app_user_id because i config 

await Purchases.setup(key,    appUserId: "my_app_user_id");

From those logs, I can’t see any errors… Is it working correctly when running from Xcode? 

@Andy

It can do it right now found it 

right now i can fetch data succuss because appUserId is invalid 

i set new right now .

Thanks you so much you suggest way to me.

you are great super hero !!

Happy to help!

Don’t hesitate to reach out again if you run into any issues. 

Have a great day!

ok thank you.

@Andy 

I found the problem same again when i use lib on version 4.0.0 

below it errror message can’t fetch offerring

flutter: information CustomerInfo(entitlements: EntitlementInfos(all: {}, active: {}), allPurchaseDates: {}, activeSubscriptions: n], allPurchasedProductIdentifiers: r], nonSubscriptionTransactions: n], firstSeen: 2022-08-11T08:41:16Z, originalAppUserId: appd40d1e398d, allExpirationDates: {}, requestDate: 2022-08-11T08:55:41Z, latestExpirationDate: null, originalPurchaseDate: null, originalApplicationVersion: null, managementURL: null)
flutter: fetchOffers error PlatformException(23, There's a problem with your configuration. None of the products registered in the RevenueCat dashboard could be fetched from App Store Connect (or the StoreKit Configuration file if one is being used). 
More information: https://rev.cat/why-are-offerings-empty, {code: 23, message: There's a problem with your configuration. None of the products registered in the RevenueCat dashboard could be fetched from App Store Connect (or the StoreKit Configuration file if one is being used). 
More information: https://rev.cat/why-are-offerings-empty, readable_error_code: CONFIGURATION_ERROR, readableErrorCode: CONFIGURATION_ERROR, underlyingErrorMessage: }, null)

in the other hand if i use lib version tomorrow is 3.10.0 not problem becasue Identifying below code

await Purchases.setup("public_sdk_key", appUserId: "my_app_user_id");

but on version 4.0.0 

PurchasesConfiguration data = await PurchasesConfiguration(key);

Why can’t set appUserId 

then i try this 

PurchasesConfiguration data = await PurchasesConfiguration(key);data.appUserID = "THIS IS MY KEY";

you know solution on 4.0.0 upper i don’t know how to config on the document still use format older version

on Changelog tell change Purchase.setup tp Puchase.configure

Tell/suggest me to use on 4.0.0 version I find solution not found.

@Panudech Changthong the old configuration method is deprecated but not removed yet, so it should still work. Are you getting an error message when using it? 

Thanks for letting us know about the outdated docs, we’ll get them updated ASAP. 

In the meantime, here’s an example of how the new configuration code should look: 

```

PurchasesConfiguration configuration = PurchasesConfiguration("your key here")
    ..appUserID = "your appUserID here";
}
await Purchases.configure(configuration);

```

You can see this being used in our sample app here:

https://github.com/RevenueCat/purchases-flutter/blob/feca797cadfd3e1abdb74f0801e5e80b61161052/revenuecat_examples/MagicWeather/lib/src/views/home.dart#L40

@Andy I can fetch data from lib current version 4.1.1 succuss

because i create core 2 main branch when i switch branch file Configuration.storekit and StoreKitTestCertificate.cer don’t in another branch which it don’t file in another , yes i can’t fetch data.

Thank you . I can implement enjoying Revenuecat.
