How to handle „pipe“ is a matter of exim, thus exim needs to know the
system_filter_pipe_transport (usually set to „address_pipe“ -- this
transport has to exist of course).
If you consult the exim spec.txt, you should find several references to
system_filter_pipe_transport and to address_pipe.

Yes, but for system filters, the pipe transport has to be set as well.

Try
exim -bP all | grep system_filter
And then try to find the mentioned transport (if any transport is
mentioned):
exim -bP transport „transport-name“
If this works, we need more ideas ;-)
