I tried your fix. Your fix just makes it not report errors. But it still cannot work correctly. Here I override WriteAnswer method. So when I execute into this logic, it will call this method to bind. But their name cannot be matched. One is protoSearch and the other is proto_search_path. So you need to modify the question name:

cwgo/cmd/dynamic/common.go

Line 79 in c081b37

Name: "protoSearch",

cwgo/config/server.go
