Not yet implemented: more media types than expected for pfsense REST API schema

Here's the schema source: https://pfrest.org/api-docs/openapi.json

Here's the build.rs I'm using to generate the source:

fn main() {
    let src = "schema/pfsense-schema.json";
    println!("cargo:rerun-if-changed={}", src);
    let file = std::fs::File::open(src).unwrap();
    let spec = serde_json::from_reader(file).unwrap();
    let mut binding = progenitor::GenerationSettings::default();
    let settings = binding.with_interface(progenitor::InterfaceStyle::Builder);
    let mut generator = progenitor::Generator::new(&settings);

    let tokens = generator.generate_tokens(&spec).unwrap();
    let ast = syn::parse2(tokens).unwrap();
    let content = prettyplease::unparse(&ast);

    let mut out_file = std::path::Path::new(&std::env::var("OUT_DIR").unwrap()).to_path_buf();
    out_file.push("codegen.rs");

    std::fs::write(out_file, content).unwrap();
}

I'm then just include!ing it inside the lib.rs that I'm going to use

This is the error output I'm getting (with some paths snipped):

failed to run custom build command for `pfsense-api v0.1.0 (/home/doni/<snip>/pfsense-api)`

  not yet implemented: more media types than expected for postAuthJWTEndpoint: 2
  note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Reproduce the failure using build.rs and schema/pfsense-schema.json, then inspect progenitor-impl/src/method.rs around the panic for postAuthJWTEndpoint. Compare the operation's two media types in the referenced OpenAPI schema and determine the expected generated output; done means generation completes without the not-yet-implemented panic and the resulting code can be included by lib.rs.
