Ok perfect thank you very much, could you explain or tell me what are the commands to decompress it or convert it to .erl? is that there are several files and I want to know so I can decompile them all,

To get the source I created a base mix project:
mix new myproject
In mix.exs deps() function I added this dependency:
{:decompilerl, github: "niahoo/decompilerl"}
Then I renamed your beam file to holiday_role_data.beam (removed the “4”) because the module inside is holiday_role_data and must match the file name.
The beam file is in the root of the project directory.
Then I created a tt.exs file with this content:
Code.append_path(File.cwd!())
Decompilerl.decompile(:holiday_role_data)
System.halt()
And then run this file with mix run tt.exs > holiday_role_data.erl
Note that you must then edit the file to remove the text “Retrieving code for holiday_role_data”.
It may be possible to have better results with GitHub - michalmuskala/decompile · GitHub because it can generate elixir source instead of erlang. But I don’t know it as much as decompilerl.

Thank you very much, very grateful, it works perfectly, but now with some files I get an error, I would like to know why? and how to fix it to be able to decompile
this is the error it gives me
** (MatchError) no match of right hand side value: {:error, :beam_lib, {:key_missing_or_invalid, <<70, 79, 82, 49, 0, 1, 52, 148, 66, 69, 65, 77, 65, 116, 111, 109, 0, 0, 4, 172, 0, 0, 0, 72, 11, 99, 104, 97, 114, 103, 101, 95, 100, 97, 116, 97, 4, 108, 105, 115, 116, 5, 108, 105, 115, ...>>, :abstract_code}}

That kind of chunk is optional in a BEAM file - it’s not usually included for “production” builds.

This is the code you have, what should I change?
defp do_decompile(beam_code) do
{:ok, {_, [abstract_code: {_, ac}]}} =
:beam_lib.chunks(beam_code, [:abstract_code])
:erl_prettypr.format(:erl_syntax.form_list(ac))
end
