Azure AD B2C cannot parse the Identity provider metadata when it contains EC keys. So, it requires exposing metadata that only contains RSA Keys. We have a feature request opened to add support for EC Keys in future but there is no ETA as of now.

Once there is an update it will be posted here: https://feedback.azure.com/forums/169401-azure-active-directory/suggestions/38510968-aad-b2c-add-support-for-ec-key-type-to-openid-con
Any update on this, I saw the other URL as well but didn;t find any update... when the support of EC type key is going to be available????
If not soon, then what is the interim solution other then asking IdP to disable it, which is kind of not doable as that impact their other applications.
