Hi Everyone, we are facing an issue while configuring the IDP metadata file. Mendix Version 7.16.0 and SAML 2.0. i have attached the console error messages. please let us know with your prior experience with cases encountering such issues about what helps to overcome this error. Note : We have compared SAML and IDP metadata with the old running Apps and we don’t see any difference between this app and older one. com.mendix.core.CoreRuntimeException: Exception occurred in
