Steps to reproduce

1. Create an something.openapi.json file with an operation using a "parameters" with a reference in it.
2. dart run build_runner build

Expected behaviour

It should behave the same as if the $ref had been inlined.

Actual behaviour

Deserializing to 'OpenAPI' failed due to: Deserializing to 'BuiltMap<String, PathItem>' failed due to: Deserializing to 'PathItem' failed due to: Deserializing to 'Operation' failed due to: Deserializing to 'BuiltList<Parameter>' failed due to: Deserializing to 'Parameter' failed due to: Null check operator used on a null value

Thanks for reporting, I will look into it soon. Can you maybe post a minimal spec that produces this error? Then it is a bit easier for me to confirm and fix it.

• Not working: broken.openapi.json
• Working (without $ref): working.openapi.json

I haven't tested the not-working one for correctness, but I think it's correct. I'll check in a few hours.

Ah yes, the problem is that we don't resolve and refs that don't point to #/components/schemas/*. I initially thought you meant a $ref inside the schema of a parameter.
