What did you expect to happen?:

Expected populated docker system info object that the last version returned.

Additional information:

Platform: Microsoft Windows 10.0.19041

Not sure if it's relevant but do have these versions of Newtonsoft.Json in the same project:

<PackageReference Include="Newtonsoft.Json" Version="12.0.3" />
<PackageReference Include="Newtonsoft.Json.Bson" Version="1.0.2" />

Getting the same error with Swarm.ListNodesAsync() in version 3.125.4

[The-TT-Hacker]

In this class here: https://github.com/dotnet/Docker.DotNet/blob/master/src/Docker.DotNet/Models/TLSInfo.Generated.cs

CertIssuerSubject is a List

It appears in the JSON returned from the docker engine as a string:

"CertIssuerSubject": "MBMxETAPBgNVBAMTCHN3YXJtLWNh"

Not sure why this is being deserialised to a list of bytes.

[gurelsoycaner]

hi, I'm having the same issue "CertIssuerSubject": "MBMxETAPBgNVBAMTCHN3YXJtLWNh" with version 3.125.4 Swarm.ListNodesAsync() Swarm.InspectSwarmAsync() Swarm.ListServicesAsync()

Can you please possibly do a fix?

Thanks in advance.

[The-TT-Hacker]

The JSON models are generated, does anyone know how this is done? Or maybe the problem is we just need a JsonConverter for base64 to byte array

Why not just download the code and fix it locally by changing CertIssuerPublicKey to string in Docker.DotNet.Models TLSInfo class. I'm not sure this is the right way, but it works for me.

[The-TT-Hacker]

Yeah that will fix it, but I don't think that change would get merged in if you submitted a pull request. That class is code generated based off the docker API schema.

Edit: I'll just submit one and we'll see what happens. This really needs to be fixed, the repo is broken and the previous version is missing quite a few features.

[The-TT-Hacker]

I just submitted this pull request: https://github.com/dotnet/Docker.DotNet/pull/469 adding a simple json converter seems to have fixed the problem for me

[dgvives]

@thnk2wn this should have be fixed in last version as @The-TT-Hacker contribution has been merged

[lippertmarkus]

@dgvives how can we bring #469 forward? This is a blocking issue for me

[dgvives]

It is fixed on master branch. Include the library not from nuget but from source code

Any update about when a fix for this issue is going to be released?

Any update about when a fix for this issue is going to be released?

I also would love to see the fix in a versioned package on nuget.org.
