I have tried to create a FB dataset with app id/app secret and FB page access token.

When I test connectivity or save rule, i get an error as below. 

App is built on Theme-Cosmos -> PegaRULES 8 and has Pega-NLP ruleset. 

How do I resolve this compilation error?  Is there a jar file missing in the installation package ?

Error from tracer :
