Hi all,  
I succeded to create a gateway network between an Ignition gateway v. 8.0.16 and an Ignition gateway v. 7.9.9. Now if I try to issue a `sendMessage` with `scope='G'` from gateway v. 8.0.16 to v. 7.9.9. the following exceptions are logged to the 7.9.9 _wrapper.log_:

_first exception_

_second exception_

Any suggestion? Different Ignition gateway versions matter?

Thanks, regards

Yes, absolutely. Sending messages between 7.9 and 8.0 requires the different gateways be at least version 7.9.14 or 8.0.11, respectively.
