I also dumped traffic in guacd_compose
container and learnt that there is a malformed VNC packet.
I am trying to connect to VNC provided by docker-selenium. I have no problem with connection using e.g. Remmina.
In the guacd troubleshooting guide I found information that:
Error instantiating client
After the client plugin is loaded, an initialization function provided by the client plugin is invoked. If this function fails, then the client itself cannot be created, and this error will be logged. Usually this indicates that one or more of the parameters given to the client plugin are incorrect or malformed. Check the configuration of the connection in use at the time.
My connection doesn't seem to have any complex options.
I increased log level in guacd

This might be the following issue.
** EDIT **
I confirm, this is a problem, it all works fine with guacamole/guacd:1.4.0
