i uploaded index.html on ufs and want to serve it using berry script, this is my current code:

class BerryFS
  def init()
    tasmota.add_driver(self)
  end
  def webrequest()
    import webserver
    try
      var fh = open(webserver.arg('file'),'r')
      # webserver.content_start("brew")
      # webserver.content_send_style()
      webserver.content_response("Content-Type: text/html;\n<html>\n" + fh.read())
      # webserver.content_response(fh.read())
      # webserver.content_stop()
      fh.close()
    except .. as e, m
      # webserver.content_response('error:'..e..' '..m)
      webserver.content_stop()     
    end
  end
  def web_add_handler()
    import webserver
    webserver.on("/fs", / -> self.webrequest(), webserver.HTTP_GET)
  end
end
var berryfs = BerryFS()

i am not able to figure out how to send headers correctly, brower will render the html as text.
i've tried the following:

just content_response of my index.html
prepending index.html with headers
using content_send_style and passing index.html souce as parameter
using content_Send_Style and content_response with index.html
using content_start() (errors out about nil)
using_content_start("string") chrome errors out with chunking error

thanks everyone for help

As I see there is by design no way with webserver to send anything in the header area.

Further I think this will never work
webserver.content_response("Content-Type: text/html;\n<html>\n" + fh.read())

webserver.content_response
This function is according documentation intended for XMLHttpRequest

Take a look to the example in the repository and start with a working example.
