Extract tar file and invalid_tar_checksum

Hi, I have downloaded a file (the file) from GitHub and wanted to extract it, but I got {:error, :invalid_tar_checksum} error. I extracted it with my Mac software, and it had no problem.

My code:

def extract(:tar, archived_file, extracted_name) do
    file = File.open!("#{extensions_path()}/#{archived_file}.tar")
    :erl_tar.extract(
      {:file, file},
      [
        {:cwd, ~c'#{extensions_path()}/#{extracted_name}'}
      ]
    )
end

OR

def extract(:tar, archived_file, extracted_name) do
    :erl_tar.extract(
      ~c'#{extensions_path()}/#{archived_file}.tar',
      [
        {:cwd, ~c'#{extensions_path()}/#{extracted_name}'}
      ]
    )
end

OR for original file

:erl_tar.extract(~c'./Downloads/mishka-group-mishka_installer-0.0.3-0-g2ba83e0.tar.gz')

Even test

Finch.build(:get, "https://codeload.github.com/mishka-group/mishka_installer/legacy.tar.gz/refs/tags/0.0.3")
|> Finch.request(DownloaderClientApi)
|> case do
  {:ok, %Finch.Response{status: 200, body: body}} ->  :erl_tar.extract({:binary, body})
  _ -> {:error, :download_tar_from_github, :not_found}
end

Thank you in advance

It needs :compressed flag

:erl_tar.extract(
  ~c'#{extensions_path()}/#{archived_file}.tar.gz',
  [:compressed, {:cwd, ~c'#{extensions_path()}/#{archived_file}'}]
)
