Error: no response content type found for deserialization

[tonven]

Hi. After calling POST endpoint which returns 204 No Content without response, I am getting Error: no response content type found for deserialization.
I am using 1.0.0-preview.75 versions of typescript library.

Thanks.

Hi @tonven
Thank you for using kiota and for reaching out.

What version of kiota has your client been generated with?

What was the last version of the package to work?

[tonven]

@baywet Thank you for response!
In a kiota-lock file it says "kiotaVersion": "1.20.0"
.NET library is 1.14.0.
It did not work because it is a new project. First time trying kiota generator :)

Thank you for the additional information.

Can you please, provide the snippet for the call you're making? as well as the API description.

Also, I'm a little confused, in your initial post you mentioned typescript version, and now a dotnet version?

@baywet Sorry for missunderstanding. I am using .NET project to generate typescript classes for my backend. To be more concrete, I am using FastEndpoints library, which runs kiota generator. Here is the source code from the library that is used:

static async Task GenerateClient(IHost app, ClientGenConfig c, CancellationToken ct)
    {
        if (string.IsNullOrEmpty(c.SwaggerDocumentName))
            throw new InvalidOperationException("A Swagger document name is required for Api Client generation!");

        var logger = app.Services.GetRequiredService<ILogger<ClientGenerator>>();
        logger.LogInformation("Starting [{lang}] Api Client generation for [{doc}]", c.Language.ToString(), c.SwaggerDocumentName);

        var swaggerJsonPath = c.CleanOutput
                                  ? Path.Combine(Path.GetTempPath(), TempFolder)
                                  : c.OutputPath;

        c.OpenAPIFilePath = await ExportSwaggerJson(app, c.SwaggerDocumentName, swaggerJsonPath, null, ct);

        await new KiotaBuilder(
                logger: LoggerFactory.Create(_ => { }).CreateLogger<KiotaBuilder>(),
                config: c,
                client: new())
            .GenerateClientAsync(ct);

        logger.LogInformation("Api Client generation successful!");

        if (c.CreateZipArchive)
        {
            logger.LogInformation("Zipping up the generated client files...");

            c.ZipOutputFile ??= Path.Combine(c.OutputPath, $"..{Path.DirectorySeparatorChar}", $"{c.ClientClassName}.zip");

            if (File.Exists(c.ZipOutputFile))
                File.Delete(c.ZipOutputFile);

            ZipFile.CreateFromDirectory(c.OutputPath, c.ZipOutputFile, CompressionLevel.SmallestSize, false, Encoding.UTF8);

            logger.LogInformation("Client archive creation successful!");
        }
    }

Here is the response from calling this endpoint:

Thank you for the additional information.

Oh wow, you've effectively build a client generation service 😮

Have you tried to generate the same client from the CLI instead and see if you're getting any difference? (in case there are differences in the setup of the builder)

Also, in your initial post you describe receiving a 204, but in the screenshot you're getting a 200. Can you double check and confirm which status code the client is receiving please?

[tonven]

I am getting 200, i mixed up with another endpoint :)
Actually the client is working perfectly, thank you! I am just ignoring this error and checking that it is 200, so this is not to a big problem at all. Was just trying to find out if it dues to older version of .NET client or a bug.
I will try to run it using CLI tomorrow and will let you know with the result
