lsp-inlayhints error

[d-e-v-esh]

I'm seeing this error and its not going away.

The lsp-inlayhints.lua (error file) looks like this:

local status_ok, hints = pcall(require, "lsp-inlayhints")
if not status_ok then
  return
end

local group = vim.api.nvim_create_augroup("LspAttach_inlayhints", {})
vim.api.nvim_create_autocmd("LspAttach", {
  group = "LspAttach_inlayhints",
  callback = function(args)
    if not (args.data and args.data.client_id) then
      return
    end

    local client = vim.lsp.get_client_by_id(args.data.client_id)
    require("lsp-inlayhints").on_attach(client, args.buf)
  end,
})

hints.setup {
  inlay_hints = {
    parameter_hints = {
      show = false,
      -- prefix = "<- ",
      separator = ", ",
    },
    type_hints = {
      -- type and other hints
      show = true,
      prefix = "",
      separator = ", ",
      remove_colon_end = false,
      remove_colon_start = false,
    },
    -- separator between types and parameter hints. Note that type hints are
    -- shown before parameter
    labels_separator = "  ",
    -- whether to align to the length of the longest line in the file
    max_len_align = false,
    -- padding from the left if max_len_align is true
    max_len_align_padding = 1,
    -- whether to align to the extreme right or not
    right_align = false,
    -- padding from the right if right_align is true
    right_align_padding = 7,
    -- highlight group
    highlight = "Comment",
  },
  debug_mode = false,
}

Does anyone know what is going on?
