I was able to reproduce this issue with a minimal repro. My guess is that this is running explicitly in GOPATH mode. This needs investigation and a fix.

Can any of you share the minimal repro case including the go.mod file? .zip file is fine.

[stamblerre]

Ah, this was my mistake - I thought that this command came from the Go extension, but it comes from the user's launch.json. I'm seeing flaky behavior - if I use the default configuration, it works fine, but if I create a default launch.json file, I see the error. I'm not sure how to see what command is being executed under the hood.

@hawkwzh: What is the contents of your launch.json?

I've attached the repro.
mod1.zip

@stamblerre
Just create launch.json, nothing changed.

I think the default launch settings are different from the generatedlaunch.json

I think I know what's going on.

Bug 1: When Run Without Debugging is invoked, resolveDebugConfiguration in goDebugConfiguration.ts is called with the initial debugConfiguration object with "noDebug": true, but it is overwritten here and the noDebug info is lost. As a result, later, I observed the debug adapter runs the program with debugging enabled (i.e. run through dlv).

Bug 2: When the debug adapter receives the request with "noDebug": true, it invokes go run <currentFIle> where the currentFile is the absolute path to the test file. And, it runs this command from the root directory /, which means the main module doesn't exist. The go run command operates in GOPATH mode and fails. So in this case, we should make the go run command to run inside the module.

I will prepare a cl.

When launch.json doesn't exist,

The fix to this is available in the latest beta version of this extension. Please do try it out and share feedback

@ramya-rao-a it's worked.
thanks.
