Generated Swagger is Empty

[VTR-AReed]

I have an existing .NET 6 Project I've been working on, and I decided to add the OpenAPI Extension and generate a swagger, however the swagger generated is empty. I have cleaned and rebuilt, I have deleted obj and bin, I have tried everything, but my same functions copied to another project work just fine, but for some reason in this project, which has no build errors whatsoever (with all trace logs on), continues to generate an empty swagger.json.

CSPROJ:

  <PropertyGroup>
    <TargetFramework>net6.0</TargetFramework>
    <AzureFunctionsVersion>v4</AzureFunctionsVersion>
    <AssemblyName>myname.Functions</AssemblyName>
    <RootNamespace>myname.Functions</RootNamespace>
    <_FunctionsSkipCleanOutput>true</_FunctionsSkipCleanOutput>
    <DocumentationFile>myname.Functions.xml</DocumentationFile>

One of my test functions:

    {
        [FunctionName("OpenAPI")]
        [OpenApiOperation(operationId: "Run", tags: new[] { "name" })]
        [OpenApiParameter(name: "name", In = ParameterLocation.Query, Required = true, Type = typeof(string), Description = "The Name parameter")]
        [OpenApiResponseWithBody(statusCode: HttpStatusCode.OK, contentType: "text/plain", bodyType: typeof(string), Description = "The OK response")]
        public static async Task<IActionResult> Run(
            [HttpTrigger(AuthorizationLevel.Anonymous, "get", "post", Route = null)] HttpRequest req,
            ILogger log)
        {
            log.LogInformation("C# HTTP trigger function processed a request.");

            string name = req.Query["name"];

            string requestBody = await new StreamReader(req.Body).ReadToEndAsync();
            dynamic data = JsonConvert.DeserializeObject(requestBody);
            name = name ?? data?.name;

            string responseMessage = string.IsNullOrEmpty(name)
                ? "This HTTP triggered function executed successfully. Pass a name in the query string or in the request body for a personalized response."
                : $"Hello, {name}. This HTTP triggered function executed successfully.";

            return new OkObjectResult(responseMessage);
        }
    }

I understand that NET.6 is not yet supported. You can run it in a NET.5 environment.

There are many .NET 6 examples linked on the main readme, and downloading and building any of them they work, (and have identical setups to my project) for whatever reason my specific project continues to generate a blank one :(

@VTR-AReed How many *.deps.json files does your Debug/net6.0/ or Debug/net6.0/bin directory have? If there are multiple *.deps.json files, it's causing the issue.

Could you confirm that on your end?

I think this issue similar #217
There is a bug and fixed recently but not deployed now.

This is the results of looking for *.deps.json

I have confirmed this to be the case, I removed the *.deps.json produced by my referenced libraries and the spec started working!

@VTR-AReed Glad it's sorted out! Please wait for a few more days until the fix #217 is released to v0.9.0-preview

[dominicusmento]

When will this new version be released? this fix is really needed.. at least as v0.8.2-preview

[janhjordie]

I'm also looking forward to get this fix. I also face the same issue on Azure

Thanks
