PyGaze error in OpenSesame using GazePoint

[13Elena98]

Hi there,

I’m working on an experiment with OpenSesame 3.3.14 running with Python 3.7 and GazePoint 6.9.0.

I have some problem with the PyGaze library. The experiment runs correctly for some trials but then slows down and I get the following message on the console:

Exception in thread PyGaze_OpenGazeConnection_incoming:
Traceback (most recent call last):
  File "C:\Program Files (x86)\OpenSesame\lib\threading.py", line 926, in _bootstrap_inner
    self.run()
  File "C:\Program Files (x86)\OpenSesame\lib\threading.py", line 870, in run
    self._target(*self._args, **self._kwargs)
  File "C:\Program Files (x86)\OpenSesame\Lib\site-packages\pygaze\_eyetracker\opengaze.py", line 405, in _process_incoming
    if not messages[-1][-2:] == '/>':
IndexError: list index out of range

I had a similar issue a few months ago. At the following link there are all the information that I previously reported directly on the OpenSesame forum (@smathot kindly helped me to fix the problem):

Do you have any suggestions?

Thanks in advance!
