Flutter - RevenueCat - There was a credentials issue, Check the underlying error for more details, error is coming after purchase

Question

I am integrating in app purchase in my flutter application through RevenueCat and to support both Android and IOS. I have followed all the steps mentioned in the documentation for configuration (https://docs.revenuecat.com/docs/creating-play-service-credentials), added subscription details, created entitlements, offerings, products in revenue cat dashboard.

In code initiated the revenue cat platform in main.dart, fetching the offerings and getting correct data, initiated purchase and it is showing payment successful but as soon as it comes back to application it is showing the error (attaching the log below) :

E/[Purchases] - ERROR(28086): 🤖‼️ There was a credentials issue. Check the underlying error for more details.

And I am getting the 1st receipt in mail from google play store and after 5 minutes I get cancellation receipt and shows the reason "Purchase is not acknowledged".

Any kind of help will be appreciated. Thanks..

Solution 1

E/[Purchases] - ERROR(28086): 🤖‼️ There was a credentials issue. Check the underlying error for more details.

The error is indicating that there's a problem with the Play Store credentials that you've uploaded to RevenueCat. Usually, this is due to the fact that it can take over a day for the credentials to propagate throughout Google - so if you recently set these up this is likely the cause.

Referencing documentation:

• Error Handline: https://docs.revenuecat.com/docs/errors#---invalid_credentials

• Play Store Credentials: https://docs.revenuecat.com/docs/creating-play-service-credentials

Solution 2

I recreated google credentials and linked the new one with revenuecat and after few hours it worked fine.

Comments

[GrahamD]

How long before testing did you set up the credentials on play store?

[Araju]

its already more than 48 hours

[Araju]

But if it was bcz of credential issue then why I am getting the product details correctly from @revenuecat through my code?

[enc_life]

Credentials aren't required to fetch products, only to validate the purchase token server-side. So the purchase will even complete with Google, but the credentials cannot validate it.

[Araju]

shall I recreate the credentials? and it will again take next 36 hours to activate?
