WSO2 IS SAML Response Missing Attribute Statement

I had tried WSO2 Identity Server integrated with QlikSense by SAML 2 Protocol .

The Statckoverflow doesn't allow embed image，Sorry.

I had setted WSO2 SP Configuration and Qliksense Server SAML2 Configuration ，but logs of Qliksense display "Exists SAML Attribute statement : 0".

The SAML authenticate process has Failed in SAML Response to Qliksense。

Also, I just found WSO2 SAML Response missing the tag of "attribute statement " 。

SAML Response(SP:QlikSense): miss attribure statement

WSO2 Log Screnshot

I think the key point is "Invalid AttributeConsumingServiceIndex in AuthnRequest "

Is it any possible edit AttributeConsumingServiceindex in WSO2 Configuration?
