Fails to generate for GitHub API

thread 'main' panicked at /home/user/.cargo/registry/src/index.crates.io-6f17d22bba15001f/progenitor-impl-0.9.0/src/method.rs:2023:23:

claims to be "openapi": "3.0.3"

I removed the unsupported content type from the spec:

            "text/x-markdown": {
              "schema": {
                "type": "string"
              },
              "examples": {
                "default": {
                  "summary": "Rendering markdown",
                  "value": {
                    "text": "Hello **world**"
                  }
                }
              }
            }

But now it fails to generate with a less helpful error:

which is emitted from this line in build.rs:
