I’m currently working on implementing the sign-up functionality in my Next.js project using AWS Cognito. However, I’ve encountered a frustrating issue. Every time I try to test the sign-up process with a brand-new temporary email address, I receive an error message that says, ‘User already exists.’ This is puzzling because I’m using a completely different temporary email each time I test it, so there shouldn’t be any existing user associated with the email address in the system. I’m not sure what might be causing this issue, and any guidance on how to resolve it would be greatly appreciated!
