Abp: CLI Broken, abp new doesn't work

[tolemac]

I have tried to use CLI to create a new template but doesn't work.

The error is raised from GetLatestSolurceCodeVersionAsync method of AbpIoSourceCodeStore:

        private async Task<string> GetLatestSourceCodeVersionAsync(string name, string type)
        {
            using (var client = new CliHttpClient())
            {
                var response = await client.PostAsync(
                    $"{CliUrls.WwwAbpIo}api/download/{type}/get-version/",
                    new StringContent(
                        JsonSerializer.Serialize(
                            new GetLatestSourceCodeVersionDto { Name = name }
                        ),
                        Encoding.UTF8,
                        MimeTypes.Application.Json
                    ),
                    CancellationTokenProvider.Token
                );

                await RemoteServiceExceptionHandler.EnsureSuccessfulHttpResponseAsync(response);

                var result = await response.Content.ReadAsStringAsync();

                return JsonSerializer.Deserialize<GetLatestSourceCodeVersionResultDto>(result).Version;
            }
        }

I have tried to make a Postman to this url:

https://abp.io/api/download/template/get-version

Using post verb and this body:

{
    Name: "Acme.BookStore"
}

And I get html response and not json as expected ...

[tolemac]

In addition direct download option at http://abp.io/get-started neither works...

[wakuflair]

I guess the version number you passed is like 0.19, but the correct format should be one digit more: 0.19.0
The error message should indeed be more specific.

[maliming]

We will fix it as soon as possible. Thanks for the feedback.

[yekalkan]

Fixed.

This issue appears to still exist, albeit getting a slightly different error message now:

Is there anything we as community contributors can do to prevent this issue from occuring? Considering that the issue is related to an API call being made to the abp.io website, I'm wondering if we could modify the command to pull the latest release from GitHub instead of depending on the website. I'm sure that the re-occurence of this kind of issue is an annoyance and pulls development time away from the project itself.

I will explore this route in the meantime but I wanted to bring this issue to your attention. Please let me know if you need any additional information to diagnose and resolve the issue. Thanks!

[hikalkan]

After v1.1 release, we will look this issue deeper to see if we can minimize external dependencies or find a fallback logic. Thanks.

BTW, you can always use "direct download" on https://abp.io/get-started when you have problems with the CLI.

[mehmetuken]

Direct download and cli new doesn't work right now. Both down.

[ismcagdas]

@mehmetuken it should be working now.

[mehmetuken]

@ismcagdas yes both working. Thanks.

[ivansager]

Gonna use direct download, CLI still not seeming to work...
