Проблема со шрифтом pillow, heroku

Как я понял, heroku не может найти шрифт. Когда запускал код на своем пк, все хорошо работало, а здесь выдаёт такую ошибку:

Фрагмент кода, где происходит работа с pillow:

img = Image.open('image.jpg')

        idraw = ImageDraw.Draw(img)

        W, H = img.size
        w, h = idraw.textsize(textforimage)

        home = Path.home()
        font_path = Path(home, "blueprints", "arial.ttf")

        headline = ImageFont.truetype(font_path, size = 30)
        idraw.text(((W-w)/2,(H-h)/2), textforimage, font=headline)

        img.save('imageandtext.jpg')
