amazon cognito - Error in SAML response processing: No SAML assertion found in the SAML response

Question

I've configured Cognito to use SAML Identity Provider and did all the setup on AD side, AD accepts the request and allow me to sign-in, then it responds to the configured idpresponse endpoint with the SAMLResponse form data value as you can see in the image below, but Cognito returns a 302 redirect with

location: http://localhost:3000/auth/callback#error_description=Error+in+SAML+response+processing%3A+No+SAML+assertion+found+in+the+SAML+response.+&error=server_error

I'm not sure what is going on, I tried to modify the POST request to idpresponse via curl and it is definitely reading the SAMLResponse form data because if I modify it I get invalid response error.

How can I troubleshoot it?
