Unable to add args to flake8

[SafetyMary]

My flake8 linter stops showing errors in neovim if i include a bare args = {} key value pair in my config. (But works in command mode "!flake8 my_script.py")

  {
    "mfussenegger/nvim-lint",
    opts = {
      linters_by_ft = {
        python = { "mypy", "flake8" },
      },
      linters = {
        mypy = {},
        flake8 = {
          args = {
          },
        },

Works fine if i commented out args = {}

  {
    "mfussenegger/nvim-lint",
    opts = {
      linters_by_ft = {
        python = { "mypy", "flake8" },
      },
      linters = {
        mypy = {},
        flake8 = {
          -- args = {
          -- },
        },

My end goal is to point it to a custom config location.

  {
    "mfussenegger/nvim-lint",
    opts = {
      linters_by_ft = {
        python = { "mypy", "flake8" },
      },
      linters = {
        mypy = {},
        flake8 = {
          args = {
            "--config",
            vim.fn.expand("~/.config/nvim/lua/plugins/.flake8"),
            "--",
          },
        },

It would work normally if i simply execute

!flake8 my_script.py --config "/home/<User>/.config/nvim/lua/plugins/.flake8"

in my case I needed to add cmd parameter. So here is configuration for markdownlint:

      local lint = require 'lint'
      lint.linters_by_ft = {
        markdown = { 'markdownlint' },
      }
      lint.linters = {
        markdownlint = {
          args = { "--disable", "MD013", "--" },
          cmd = { 'markdownlint' }
        },

      }

So probably your config should look like

  {
    "mfussenegger/nvim-lint",
    opts = {
      linters_by_ft = {
        python = { "mypy", "flake8" },
      },
      linters = {
        mypy = {},
        flake8 = {
          args = {
            "--config",
            vim.fn.expand("~/.config/nvim/lua/plugins/.flake8"),
            "--",
          },
         cmd = {'flake8','my_script.py'}
        },

I tried adding cmd parameter but it did not help. Having bare args = {}, still stops flake8 from showing errors in neovim.

  {
    "mfussenegger/nvim-lint",
    opts = {
      linters_by_ft = {
        python = { "mypy", "flake8" },
      },
      linters = {
        mypy = {},
        flake8 = {
          cmd = "flake8",
          -- only works if the args parameter is removed
          -- args = {
          -- },
        },
