RuntimeError: invalid msg port in connect() or disconnect()

Hey everybody,

 

I am currently facing the following error:

 

Could not find port: time_per_angle_message in:
system

Traceback (most recent call last):
  File "/home/theow/GNURadio/flowgraphs/transceiver_station_2.py", line 561, in <module>

RuntimeError: invalid msg port in connect() or disconnect()

 

I googled a lot, but I did not really find an answer to that problem...

I am on an older setup with gnuradio 3.7 and ubuntu 16.04. I know for sure, that this setup was already working...so I am even more confused about that error.

 

Would be very great if anyone had maybe a quick idea, how to solve this error. If you need any more information, I will gladly provide it.

 

Thanks in advance,

Theo
