Error: Register namespace operation failed.
Error Details: rpc error: code = InvalidArgument desc = Invalid cluster name: active

Can someone suggest how to resolve this issue?

Hi @wanghaotime

this is the first time I see this error, but I think you are missing the active cluster name?

Let me know if it helps,
