Describe the bug

@server(
    group: user
    prefix: user
    jwt: JwtAuth
    middleware: Authorization, Casbin
)

service manage {

    @doc "user list"
    @handler List
    post /list (UserListRequest) returns (UserListResponse)

    @doc "create user"
    @handler Create
    post / (CreateUserRequest) returns (CreateUserResponse)

}

goctl api go -api *.api -dir ../  --style=goZero

syntax error: expected ':' | 'IDENT' | 'INT', got '('

The location of the problem is

    post / (CreateUserRequest) returns (CreateUserResponse)

Expected behavior

post / 

The goctl API seems to force me to write an address, hoping that previous versions do not force me to write an address
