formatted_text() is generate "Prawn::Errors::UnknownFont"

[Mr. Alone]

Hi All.

I'm need help.

I get an error when I call the function 

formatted_text(

[

{ text: 'text1', font: 'TiemposHeadline', size: 10, styles: [:medium] },

{ text: 'text2', font: 'TiemposText', size: 10, styles: [:regular] }

]

)

Prawn::Errors::UnknownFont in TestController#show

is not a known font.

class MyPdf < Prawn::Document

  def initialize()
    super(page_size: 'A4',
          page_layout: :portrait,
          margin: 20
    )

    font_path = "#{Rails.root}/app/assets/fonts"
    font_families.update(
      "TiemposText" => {
        :regular => { :file => "#{font_path}/Tiempos/TiemposText-Regular.ttf" },
        :italic => { :file => "#{font_path}/Tiempos/TiemposText-Italic.ttf" },
        :bold => { :file => "#{font_path}/Tiempos/TiemposText-Bold.ttf" },
        :bold_italic => { :file => "#{font_path}/Tiempos/TiemposText-BoldItalic.ttf" }
      },
      "TiemposHeadline" => {
        :medium => { :file => "#{font_path}/Tiempos/TiemposHeadline-Medium.ttf" },
        :light => { :file => "#{font_path}/Tiempos/TiemposHeadline-Light.ttf" },
        :italic => { :file => "#{font_path}/Tiempos/TiemposHeadline-Italic.ttf" },
        :bold => { :file => "#{font_path}/Tiempos/TiemposText-Black.ttf" }
      },
      "Poppins" => {
        :regular => { :file => "#{font_path}/Poppins/Poppins-Regular.ttf" },
        :medium => { :file => "#{font_path}/Poppins/Poppins-Medium.ttf" },
        :medium_italic => { :file => "#{font_path}/Poppins/Poppins-MediumItalic.ttf" },
        :light => { :file => "#{font_path}/Poppins/Poppins-Light.ttf" },
        :italic => { :file => "#{font_path}/Poppins/Poppins-Italic.ttf" },
        :bold => { :file => "#{font_path}/Poppins/Poppins-Bold.ttf" },
        :semi_bold => { :file => "#{font_path}/Poppins/Poppins-SemiBold.ttf" },
        :semi_bold_italic => { :file => "#{font_path}/Poppins/Poppins-SemiBoldItalic.ttf" }
      }
    )
