When we receive a SAML response assertion from an Identity Provider and it’s missing one or more of the required attributes, the error could be more specific.  

Currently, it just says: “Something went wrong         The response assertion is missing a required attribute”

We recommend adding the names of the missing attributes in the error message.  It would save time with troubleshooting.

For example, it could read as follows: “Something went wrong         The response assertion is missing a required attribute: <Attribute Name>”
