Hi,

hm, could just tell me if I am thinking wrong, but this looks like some of my blocks is also called in_port?

Hi Nemanja,

a blind suspicion: as "system" is a port that should be registered by the runtime for each block, there might be some confusion happening.
Does it work better when you rename your block to something else?

Best regards,
Marcus

Hi all guys,

I recently installed 3.7.8, and before that I had 3.6.5.1.
I was using message passing in some of my blocks, but now I get error which is following:

Could not find port: in_port in:
in_port
system

Traceback (most recent call last):

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

I see that there is a function for checking whether the ports are valid, but don't get what's wrong with my ports. Namely, I have hier block and a few blocks are sending messages to a single blocks where the messages are decoded and written to darabase. I tried to hardcode names of the blocks and that also didn't help.

Thanx,
