Hi Mauricio --

It looks like you are getting 2 different errors, at 2 different test points...

For the logical comparison error ("can't use empty string..."), you might try enclosing the "RTSP::header exists" function in () before negating it:
when RTSP_REQUEST {
  if { !([RTSP::header exists "sesion"])}{
    RTSP::header insert sesion 1
    if {[RTSP::header value "User-Agent"] starts_with "MOT-"} {
      pool VIDEOSTR_HELIX_RM
      log VIDEOSTR_HELIX_RM
    } else {
      pool VIDEOSTR_HELIX_GATEWAY
      log VIDEOSTR_HELIX_GATEWAY
    }
  }
}
Not sure about the other. Usually means a node has already been selected and you're trying to re-select another without detaching first. The solutions I've seen for that are either to add a OneConnect profile to the virtual server or to add the "LB::detach" command to the iRule immediately before choosing a new node/pool.
