Describe the bug

When Cognito user pool client id changes, new sign-in tries to create new cookie elements. Eventually it gets larger. Then CloudFront blocks it.

One possible solution would be clearing all Cognito related cookies before new signin.

There are already two tickets for this matter. But Amplify team seems ignore them. Not customer obsessive :)

Expected behavior

No server-side error must happen.

Reproduction steps

To reproduce:

1. Log in to your app using Cognito.
2. Change the client id in Cognito.
3. Login again.
4. Repeat 1.

After 3rd iteration you get the error message from the CloudFront.

@adilek Are you using Cognito Hosted UI?

@adilek Are you using Cognito Hosted UI?

We do not use hosted UI due its limitations. Instead we use APIs from Amplify to work with Cognito.

Hey @adilek 👋 thanks for raising this issue. We've opened an internal ticket with the Cognito team to see if this can be addressed on the service side or if they have any feedback/recommendations on how to mitigate it. Will respond back with any updates.

I'm also getting this, CloudFront error is "494 ERROR The request could not be satisfied.", for what it's worth it.

LocalStorage is not a secure option for session storage and is discouraged by OWASP, it's a shame that after several years the Amplify/Cognito teams haven't addressed this. The first issue I could find on this dates from as early as Feb 2018.
