Describe the bug

VSCode debugger uses wrong paths for some files during remote attach debug session. This only happens with few files. Debugger some how assumes the file path is pkg/rpc/pkg/rpc/context.go while the actual file path is pkg/rpc/context.go and it fails to locate the file.

Steps to reproduce the behavior:

I'm not sure if there is an easy way to reproduce this but I can provide additional information as needed. Sharing launch.json file contents here:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Attach to Process",
            "type": "go",
            "request": "attach",
            "processId": "${command:pickProcess}",
            "mode": "local",
            "cwd": "/mnt/workspace/github.com/cockroach",
            "substitutePath": [
                {
                    "from": "/mnt/workspace/github.com/",
                    "to": "github.com/cockroachdb/"
                },
            ]
        },
    ]
}

Thanks for reaching out @cthumuluru

VSCode debugger uses wrong paths for some files during remote attach debug session. This only happens with few files.

Can you please tell us more about how you built the debugged binary?

And, can you query the problematic source files's paths recorded in the binary from the DEBUG CONSOLE? For example,

To run this dlv sources command, you will need to pause the debug target or stopped on a breakpoint first.
