Decoding error when loading amplify credentials: KeychainStoreError

[andr3a88-amk]

Describe the bug

Hi, I've updated Amplify Swift from 2.43.0 to 2.45.1. When I run my app with the updated of Amplify I cannot fetch the access token (causing a force logout to the user). I fetch the access token calling cognitoTokenProvider.getCognitoTokens().get()

From Xcode console i noticed this log:

Error when loading amplify credentials: KeychainStoreError: Error occurred while decoding AWSCredentials
Recovery suggestion: This should not happen. There is a possibility that there is a bug if this error persists. Please take a look at https://github.com/aws-amplify/amplify-ios/issues to see if there are any existing issues that match your scenario, and file an issue with the details of the bug if there isn't.

@andr3a88-amk Would you be able to share the entire verbose log? If possible, would you also be able to share the verbose logs when it was working in the earlier version.

Also did the config change from 2.43.0 to 2.45.1?

[harsh62]

@andr3a88-amk I am able to reproduce the issue. I am working on a fix and will update as soon as I have a fix ready.

A fix has been released for the issue. https://github.com/aws-amplify/amplify-swift/releases/tag/2.45.2

[andr3a88-amk]

@harsh62 I can confirm that the issue is no longer present on 2.45.2
