Intermittent "Network Error" with AWS Cognito node SDK

Question

A few hours ago my system's integration with Cognito started failing with a simple "Network Error" message. This integration has been live and working without any issues for over a year now, and there have been no recent code changes or configuration changes in the AWS console; I think it can be a temporary instability on Cognito's side, but AWS status pages are not reporting any issues.

The issue is affecting my users' ability to log in to our platform, how can I confirm it is a Cognito-side issue or if not, how can I find and fix the issue?

Answer

Has anyone looked into this further? I'm also experiencing a similar issue where user authentication through amazon-cognito-identity-js (this is done within a AWS Lambda function) is failing intermittently. The majority of the authentications are succeeding however which is making me scratch my head. Is this a cognito issue or an issue on our side? The errors started to happen after upgrading our node version from 14 to 20.

UPDATE: All login attempts are now failing with "Network Error" message. I still can't find a reason.
