CTC1030 - Object reference not set to an instance of an object

[omni-htg]

Similar to the experience in #276 , my coworker is currently experiencing this error:

Code: CTC1030
Description: Object reference not set to an instance of an object
File: Container.targets
Line: 215

when trying to start debugging a project from the first time they open the solution. In order to make it work, they have to Uninstall and Install the package.

They do have a %Temp%\Microsoft.VisualStudio.Containers.Tools folder, but after triggering the issue again, no log has been generated.

In any case, I can provide the latest entries found in the %Temp%\Microsoft.VisualStudio.Containers.Tools folder:

{
  "timestamp": "2024-06-06 10-20-52.316",
  "message": "An error occurred checking to see if a Docker image can be built.",

And the %Temp%\Microsoft.VisualStudio.Containers.Tools.Extensions folder:

    "HResult": -2146233079,
    "Source": "Microsoft.VisualStudio.Containers.Tools.Extensions.Shared",

}

Their environment is:

• Windows 11
• VS 2022 17.9.6
• ContainerTools 1.20.1
• Docker Desktop 4.30.0

Thank you for your assistance!

Hello @omni-htg,

I attempted to repo the issue myself and was unable. There is a chance there might be some more info logged in the <ProjectDirectory>\obj\Container\ContainerToolsExceptions.json file but I'm doubtful.

Two things that could help narrow down what the issue might be: 1) Upgrade to VS 17.10 and see if the issue persists. 2) Downgrade the ContainerTools NuGet to 1.19.6

If none of those seem to help, I think I'll need a dump file to debug what is going on. When the exception occurs, at the top of VS select Help -> Send Feedback -> Report A Problem then open an issue on developer community. There you can upload files/messages privately.

Hey @patverb ! We can try tomorrow, see where it takes us.

I'll need a dump file to debug what is going on

How can we generate this?

Thanks!

Hello @patverb ! Apologies for the delay. They have updated VS to 17.10.2 and now it doesn't throw the exception again, so we can close this issue out.

When I have time in the following days I will try to install that version of VS again and run the project that failed to try and fish out the <ProjectDirectory>\obj\Container\ContainerToolsExceptions.json file.

Thank you for your assistance.
