OpenAPIParser or OpenAPIV3Parser could not parse petstore openapi 3.1 spec #2115

Open rajakumar17 opened 1 month ago

rajakumar17 commented 1 month ago

I am using swagger parser to parse various openapi specifications. OAS2.0 and 3.0 specifications works fine. However, OAS3.1 specification fails to parse.

        <dependency>
            <groupId>io.swagger.parser.v3</groupId>
            <artifactId>swagger-parser</artifactId>
            <version>2.1.22</version>
        </dependency>

Code sample

        ParseOptions parseOptions = new ParseOptions();
        parseOptions.setResolve(true);
        parseOptions.setResolveFully(true);
        SwaggerParseResult result = new OpenAPIParser().readLocation("https://petstore31.swagger.io/api/v31/openapi.json", null, parseOptions);
        OpenAPI openAPI = result.getOpenAPI();

        if (result.getMessages() != null) {
            result.getMessages()
                  .forEach(System.err::println); // validation errors and warnings
        }

        if (openAPI != null) {
            final Map<String, Schema> schemas = openAPI.getComponents()
                                                       .getSchemas();
            schemas.entrySet()
                   .stream()
                   .forEach(this::printSchema);
        }

Category object is part of the same specification json. This is looking at the wrong location.
