I build using this ansible role and have no such issues. In fact I just rebuilt a server using that and verified mod_dialogflow loads fine.

I suggest you use that ansible role, or if you do not use ansible, look carefully at what it does and the various repos and tags/versions that it uses. Its important to get the version of grpc and googleapis that match the mod_dialogflow code. (But its simpler to use ansible, and if that is not in your bag of tricks currently I highly recommend you pick it up)
