Why are errors in authentication using Identity providers with cognito not forwarded to callback urls ?

Hi peeps, I have a user pool on my cognito service and it is having Google as an identity provider. And this user pool has web client which handles the login and registration using AWS amplify. The web client's url is given in the callback url in the user pool configuration. Now whats happening is if there is an error in the SSO flow, the error lands on the hosted UI (which is expected), but only few errors are redirected to callback urls and others not. So what happens is for errors A,B,C the callback url is called where the UI app shows the error message. And for D,E,F errors the hosted UI shows 'Something went wrong' message without redirecting to callback url.

1. I have tried to disable hosted UI but I need the url for the google sso integration where the /idpresponse is called from google
