Running into issues customizing a theme

[lokesh-krishna]

I am following the instructions provided in the readme for customizing themes and have the following in my init.vim:

lua << EOF

local custom_catppuccin = require'lualine.themes.catppuccin'

custom_catppuccin.normal.c.bg = '#1e1e28'
custom_catppuccin.normal.c.fg = '#1e1e28'

require("lualine").setup {
  options = {
    icons_enabled = true,
	disabled_filetypes = {'NvimTree'},
    theme = 'custom_catppuccin',
    component_separators = '|',
    section_separators = { left = '', right = '' },
  },
  sections = {
    lualine_a = {
      { 'mode', separator = { left = '' }, right_padding = 2 },
    },
    lualine_b = { 'filename', 'branch' },
    lualine_c = { 'fileformat' },
    lualine_x = {},
    lualine_y = { 'filetype', 'progress' },
    lualine_z = {
      { 'location', separator = { right = '' }, left_padding = 2 },
    },
  },
    inactive_sections = {
      lualine_a = {'filename'},
      lualine_b = {},
      lualine_c = {},
      lualine_x = {},
      lualine_y = {},
      lualine_z = {'location'}
  },
  tabline = {},
  extensions = {}
}
EOF

However, when reloading Neovim, I get the following error:

Theme `custom_catppuccin` not found, falling back to `auto`. Check if spelling is right.

Should I be specifying this somewhere other than my init.vim?

You need to pass the table not tables name

-theme = 'custom_catppuccin',
+theme = custom_catppuccin,

Thank you so much!
