Golang VSCode configuration best setup

Question

I wonder if someone can share their best setup for Golang using Vscode on Mac. As I am continously having issues such as:

1. sometimes gomft doesn't work.
2. Functions defined in the same package shows with a red underline warning saying it's not defined (but works when running it)
3. having the following message popped up

Your workspace is misconfigured: command-line-arguments has no metadata. Please see https://github.com/golang/tools/blob/master/gopls/doc/troubleshooting.md for more information or file an issue (https://github.com/golang/go/issues/new) if you believe this is a mistake.

Here are some information of my go setup:

• Version: go1.13.4 darwin/amd64
• Settings in 'settings.json':

    {
        "window.zoomLevel": 1,
        "workbench.iconTheme": "material-icon-theme",
        "editor.accessibilitySupport": "off",
        "go.useLanguageServer": true,
        "go.formatTool": "gofmt",
        "go.lintTool": "golangci-lint",
        "[go]": {
            "editor.formatOnSave": true,
            "editor.codeActionsOnSave": {
                "source.organizeImports": true
            },
        },
        "explorer.confirmDragAndDrop": false,
        "javascript.updateImportsOnFileMove.enabled": "always",
        "diffEditor.ignoreTrimWhitespace": false
    }

• GOPATH is pointing to the folder where Go is installed
