I'm afraid my answer was incorrect. I had the wrong impression that
mysql group replication did not accept tables with not exactly one
primary key (we have a table with two primary keys) but it turns out
it requires _at least_ one primary key, and our schema should work.

There should be a more detailed error in the group replication plugin
logs, can you check what error gets reported there?

That's fine. I will have a look at it shortly.

Thanks,
