SchemaTypeRef field wrong set nil

[leyserai]

hello,
When I parse a swagger json, the request body refer to an object, such as #/components/schemas/TeacherAdmitWay,
but the SchemaTypeRef in pathItem.Post.RequestBody.Schema is nil.

the attachment is the json file. the code below

document, err := libopenapi.NewDocument([]byte(fiddleCommon.SwaggerJson))
	if err != nil {
		panic(fmt.Sprintf("create document failed: %v", err))
	}

	document.SetConfiguration(&datamodel.DocumentConfiguration{
		BundleInlineRefs: true,
	})
	docModel, errors := document.BuildV3Model()
	if len(errors) > 0 {
		for _, err := range errors {
			fmt.Printf("error: %v\n", err)
		}
		panic(fmt.Sprintf("errors %d", len(errors)))
	}
for pair := docModel.Model.Paths.PathItems.First(); pair != nil; pair = pair.Next() {
		path := pair.Key()
		pathItem := pair.Value()
		fmt.Printf("路径: %s\n", path)

		 
		if pathItem.Post != nil {
			fmt.Printf(" %s\n", pathItem.Post.Description)

			 
			if pathItem.Post.RequestBody != nil {
				parseRequestBody(pathItem.Post.RequestBody, &docModel.Model)
			}
             }
func parseRequestBody(requestBody *v3.RequestBody, docModel *v3.Document) {
	if requestBody.Content != nil {
		for pair := requestBody.Content.First(); pair != nil; pair = pair.Next() {
			contentType := pair.Key()
			mediaType := pair.Value()
			fmt.Printf("      %s\n", contentType)

			if mediaType.Schema != nil {
				parseSchema(mediaType.Schema.Schema(), "        ", docModel)
			}
	if schema.SchemaTypeRef != "" {
		fmt.Printf("%s: %s\n", indent, schema.SchemaTypeRef)
		refSchema := resolveRef(schema.SchemaTypeRef, docModel)
		if refSchema != nil {
			parseSchema(refSchema, indent+"  ", docModel)
		}

	}
		}
	}
}

In Schema.Build method, the code blow
_, schemaRefLabel, schemaRefNode := utils.FindKeyNodeFullTop(SchemaTypeLabel, root.Content)
SchemaTypeLabel is "$schema", but not found in the json file.

attache json file:
test.json

Could you provide a simplified example? Also, why do you use refSchema: = resolveRef (schema. SchemaTypeRef, docModel)? The library provides a proxy to fetch the schema if it is a reference. I would understand the logic if it was a polymorphic schema (oneOf, allOf, anyOf), but I am missing the example.

I can't quite figure out what it is you're trying to do here. Honestly I need a working sample I can try out to determine what it is you're struggling with.

I have tried your code and it won't compile, due to missing functions etc.
