Issue with LTI Certification Test Suite: Deep Linking UI Flow

Issue with LTI Certification Test Suite: Deep Linking UI Flow

Hi! I am testing my tool against the Certification Test Suite and I'm getting the following message in the second test(Submitted Deep Linking Response Payload was Received) :

crtrsaprovider was NULL As a result the jwt to use is NULL

I am not sure what this message means but I am guessing that it might related to the JWK. Does anyone know what this message means?
