Hello,
why do this not work?
If I create one single statement everything is fine!
Thank you
That’s just a generic message for an internal error that was caused by some Python API call.
Could be due to any number of reasons, but since you are clearing the routine I suspect you are trying to use a deleted object e.g a statement.
Hey TSy,
you were right. Clear the main routine in the loop was the mistake. The day was already too long. 
Thank you
