[keycloak-user] ParsingException Unknown xsi:type

Hi, I'm trying to setup my keycloak as SAML broker identity with external IDp but with no luck. I've setup my Identity Provider with IDP FederationMetadata/2007-06/FederationMetadata.xml. I login with external Idp successfully but after Keycloak receives SAML Assertion  I'm getting some Parser exception [1] Could you  please provide me some solution? Thank you 1.
