CORS problems when redirect in Azure B2C

Question

Good Morning,

we are developing an Azure B2C tenant with custom policies and we are facing a problem when we want to automatically redirect from the web portal to the Azure B2C showing this error:

Access to XMLHttpRequest at 'https://XXXXXXXXX.b2clogin.com/XXXXXXXXXX.onmicrosoft.com/oauth2/v2.0/authorize?p=B2C_1A_SIGNUP_SIGNIN&client_id=c94c14cd-4efc-4c34-a70b-f88e9aa5877b&redirect_uri=https://XXXXXXXXX/XXX/XX/inici.html&scope=openid%20offline_access&response_type=code&promt=login&response_mode=query&ui_locales=ca&origin=https://XXXXXXX/XXX/XX/XXXXX/XXXXXX?eventId=a0da3b0e-90e2-4b8a-95ca-f50654ec9bd6&languageId=51d9383e-1039-ed11-9db1-00224899347c' (redirected from 'https://XXXXXXXXX/XXXXX/XXXXXX/XXXX/XXXXX/XXXXXXXX/jcr:content.user-info.json?eventId=a0da3b0e-90e2-4b8a-95ca-f50654ec9bd6&languageId=51d9383e-1039-ed11-9db1-00224899347c') from origin 'https://XXXXXXXX' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

We have reviewing the Azure B2C settings and we dont see any CORS configuration where we can configurate CORS policies.

Regards.
