staticcheck raising errors in neovim

Question

The staticcheck analyses aren't appearing in my Neovim setup. My expectation is that I'd see a finding for the strings.Replace call in the screenshot, but I do not. Instead, I see the following:

gopls configuration

["gopls"] = function()
    require('lspconfig').gopls.setup({
        settings = {
            gopls = {
                analyses = {
                    unusedparams = true,
                },
                completeUnimported = true,
                staticcheck = true,
                gofumpt = true,
            }
        }
    })
end

Debug steps

• Ensured staticcheck is installed
• Ensured staticcheck has findings for the file (staticcheck ./...)
• Ensured gopls is setup by validating that gofumt works (i.e., created a formatting issue gofmt doesn't care about but gofumpt does care about, and it becomes formatted correctly)
• Checked that native gopls findings work (e.g., creating an unused variable)
• Restarted Neovim
• Tried setting the static check using ["ui.diagnostic.staticcheck"] = true instead of staticcheck = true
• Set the go version in the go.mod file in case there were any version mismatches.
