Hi,
I understand you configured a virtual channel and experienced the same behavior, which leads me to believe that it is either a setting or part of the program architecture that is causing the issue. Below, I have included a link to a community example on our website.

I would recommend trying this code and setting the clock to finite samples (30000) to see if you still encounter the same error.
I hope this helps!
