Unhandled internal error - While opening plugins manager

Builder
1

OS (e.g. Win10): Win11Pro
PsychoPy version (e.g. 2024.2.4 Py 3.8): 3.10
Standard Standalone Installation? (y/n) If not then what?: Y
Do you want it to also run online? (y/n) N
What are you trying to achieve?: 1) Follow this tutorial (Sending triggers via EGI NetStation — PsychoPy v2025.2.4). I am trying to install the EGI NetStation-PY plugin and then run the hardware demo experiment to see if triggers are being sent to the EGI NetStation system.

  1. Also, when I click on PyschoPy updates, it says that there is no internet connection despite there being one. It is not protected by firewall of any kind.

Please let me know if there is any other way to check the trigger marking other than this tutorial.

What did you try to make it work?: I am using the latest PsychoPy version (2025.2.4)

Link to the most relevant existing thread you have found: Psychopy builder plugin/packages manager problem - Builder - PsychoPy (this suggests using an older version 2024.2.4 - should i just do that?)

What specifically went wrong when you tried that?:

When I try to produce a JS version of my Python Psychopy experiment I get an error that contains a similar line:
for plugin in _packageIndex[‘available’][‘plugins’][‘packages’].values():
TypeError: ‘NoneType’ object is not subscriptable

Here is the whole exception traceback:

If you know the name of the package you want to install you could try this from the Coder view in the Shell panel:

>>> from psychopy.tools import pkgtools
>>> pkgtools.installPackage( 'egi-pynetstation' )

BUT I think egi-pynetstation might be getting packaged already. You could check that from the same Shell view with

>>> import egi_pynetstation
>>> egi_pynetstation.__version__
'1.0.0'
