Cognito Hosted UI - Forgot password functionality is broken on Hosted UI
Hello Cognito users,
I have two apps that use AWS Cognito. One of the registered users complained that they are not able to reset the password and get an error on the screen. I too was able to reproduce this issue. Anyone else also facing this issue? The error says "Unrecognizable lambda output". I don't have custom lambda for reset password function which makes the error strange.
- I have a custom domain for my auth.
- I have one lambda trigger for PostConfirmation_ConfirmSignUp which hasn't changed in months.
- No recent changes.
Attaching the screenshot of the error. It happens attempting to reset the password.

Found the issue. Putting it out here so that others can benefit. I had the Post confirmation Lambda trigger where I was only checking for PostConfirmation_ConfirmSignUp event. I did not expect that the lambda will also be triggered for PostConfirmation_ConfirmForgotPassword event. I fixed it by returning the event for both types of events. I overlooked the documentation and thus thought that the functionality was broken.
