I can successfully parse the Appointment JSON parse example after rerunning Library Resource is added to the channel. I noticed that I can successfully create the Hapi FHIR context in the Destination connector. It fails to create the Hapi FHIR context in the Global Deploy Scripts. It's beneficial to do this in the Global Deploy Scripts since this object instantiation is expensive. This fails in Global Deploy Scripts: Succeeds in Destination Connector: Global Deploy Scripts export: Channel export: |

The global script doesn't know about the resource libraries. Just do your $g setup in the first channel you deploy.. |

I forgot we can add the Library Resources to the Global Scripts. Now I can create the Hapi FHIR context in the Global Deploy Scripts and save it to the Global Map. Thank you very much! I greatly appreciate your help! |

@phommata sorry - I meant if you put it in a single channel it instantiates once. The Global Deploy script would run on every deploy. |

Oh, I see. Single instantiation in a channel would be better than running on every deploy in the Global Deploy script. |
