If you look at the logs you'll see the SRV record content is not correct.
It works if you supply correctly formed SRV records (in presentation format).
In particular, a SRV record has three numbers and then a name.
I just tried
srv.example.net 10 IN LUA SRV "view({{{'127.0.0.1'},{'10 20 999
k8s-plane1.example1.com.'}},{{'0.0.0.0/0'}, {'10 20 999
k8s-plane1.DEFAULT.'}}})"
And it worked as expected.
