Сan't convert large file (~100k rows in HTML)

[YuraAfanasyev]

When I try to convert a large file (~100k rows in HTML), I get an error:
stack level too deep
my code is:

respond_to do |format|
  format.docx do
    render docx: 'report', filename: "report.docx"
  end
end

Small files are generated perfectly.

If I change the code to this:

respond_to do |format|
  format.docx do
    html = render_to_string template: 'report', formats: :docx
    result = Htmltoword::Document.create(html)
    send_data result, type: "application/vnd.openxmlformats-officedocument.wordprocessingml.document", filename: "report.docx"
  end
end

then the rails server is stopped with error:

/Users/developer/.rvm/gems/ruby-2.5.1@plutus/gems/htmltoword-1.1.0/lib/htmltoword/document.rb:104: [BUG] Illegal instruction at 0x00007fff7164f5e2

I tried using different versions of rails and ruby, but this does not work. Other gems, such as pandoc-ruby, convert such large files, but text formatting does not work in them.

We have the same issue. @YuraAfanasyev have you found a solution yet?
