Nagging error: 'unable to extract attributes, unknown XML object type: saml2p:Response'

[Paul Wilt]

I have been trying figure out why we are getting this error in our
shibd.log for the French federation (renater.fr):

2016-11-30 10:44:38 DEBUG OpenSAML.SecurityPolicyRule.XMLSigning [7]:

I checked back through our signature.log and it appears that this started
happening on 2016-07-11 (July 11).

I have tried to figure this out but am currently stymied.

Any help would be greatly appreciated!
