Error 500 (INTERNAL_SERVER_ERROR) means it is a server error. Did you try running the same query against contentful server manually?

Also this error:

reason: self signed certificate in certificate chain

Run this command : export NODE_TLS_REJECT_UNAUTHORIZED=0 

hints that you may have some kind of self-signed root SSL certificate on the machine where you try to build the site?
