Fiori SSO with ADFS

Dear colleagues,

We have configured SP initiated SSO Fiori with ADFS IDP.

We are getting below error in the logs,

CX_SAML20_ASSERTION: Attribute 'SessionIndex' of element 'AuthnStatement' does not exist. Long text: Attribute 'SessionIndex' of element 'AuthnStatement' does not exist.

Please provide the inputs to fix the issue.

Regards,

Sree
