Question: I setup fabric-explorer according to the README.md,
Everything go well except an error reported above when I execute node main.js to try to setup the fabric-explorer server. Thanks: If maintainers see this, help me :-). It will be much appreciated.

Hello, I have this also, but it is because I don't have a CA server I think. We don't use the CA server as we're using the generated certificates as is. So we don't enroll our user with login/password but directly with the certificates. Is it supported?
