Hi Theo,
I assume this setup is part of a very old experiment that you want to
reboot. However, something must have changed since it's broken at the
moment.
It is very difficult to spot the issue without any context but just a
traceback.
The message itself tells you that you try to connect a message port
that's not an actual message port.
GRC generates a Python file for your flowgraph. In your case you also
have a hier block that receives a second Python file. The error happens
in there:
File "/home/theow/.grc_gnuradio/RX_SC_PHY.py", line 91, in __init__
self.msg_connect((self, 'time_per_angle_message'),
(self.theomodule_set_array_and_tt_RX_0, 'time_per_angle_message'))
This hier block is potentially called "RX_SC_PHY". You might want to
check what happened there.
Cheers
Johannes

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
