fhir schema knowledge base

[Vkodthiv]

I am tasked with using graphQL mesh for FHIR resources. I am following the example code at https://github.com/Urigo/graphql-mesh/tree/076813cbf0ec90dbb67514a2c0b5ebcfed13047b/examples/json-schema-fhir

I started by deleting a few example graphql queries to pare down what is needed for my project. However yarn start throws an error
subSchema: { description: "xhtml - escaped html (see specfication)", title: "xhtml" } path: "/properties/query/properties/resourceByName/properties/entry/items/properties/resource/oneOf/0/properties/text/properties/div" 🕸️ - FHIR: Failed to generate schema: Cannot read properties of undefined (reading 'getTypeName') 🕸️ - FHIR: TypeError: Cannot read properties of undefined (reading 'getTypeName');

Is it my lack of understanding FHIR ? or is it something else with my configuration ?

Why did you remove those operations from the config? It breaks the project because as you can see the operations you removed are being used in additionalResolvers. You can delete example operation documents but you need to leave mesh configuration as-is

I am slightly confused between the two patterns available for FHIR. I assume "fhir" handler is only meant for FHIR servers and "jsonSchema" handler will work conveniently with non compliant FHIR servers (???)

We don't have a FHIR handler(we used to have one but it is not needed anymore). We only have JSON Schema handler that generates GraphQL Schema by using JSON Schemas provided by FHIR

@ardatan I am still trying to understand how graphQL schema works. Give me a few hours while i catch up on your earlier comment
