no data in mongodb

[wms3001]

When there is no data in mongodb, the program currently throws an exception directly. I suggest that the normal situation is to return the information through error. 2024/01/27 17:48:29 Query: db.order.Find.One.conds(map[orderId:1046505705]) Stack: fmt.(*pp).handleMethods@C:/Program Files/Go/src/fmt/print.go:673 fmt.(*pp).printArg@C:/Program Files/Go/src/fmt/print.go:756 fmt.(*pp).doPrint@C:/Program Files/Go/src/fmt/print.go:1211 fmt.Append@C:/Program Files/Go/src/fmt/print.go:289 log.(*Logger).Print.func1@C:/Program Files/Go/src/log/log.go:261 log.(*Logger).output@C:/Program Files/Go/src/log/log.go:238 log.(*Logger).Print@C:/Program Files/Go/src/log/log.go:260 ggrpc/data/order.(*Order).FindOrder@C:/glkj/golang/ggprc/data/order/order.go:65 ggrpc/server/order.(*Order).PushOrder@C:/glkj/golang/ggprc/server/order/order.go:18 ggrpc/proto/order._Order_PushOrder_Handler.func1@C:/glkj/golang/ggprc/proto/order/order_grpc.pb.go:86 ggrpc/server.unaryInterceptor@C:/glkj/golang/ggprc/server/register.go:59 ggrpc/proto/order._Order_PushOrder_Handler@C:/glkj/golang/ggprc/proto/order/order_grpc.pb.go:88 google.golang.org/grpc.(*Server).processUnaryRPC@C:/Users/Administrator/go/pkg/mod/google.golang.org/[email protected]/server.go:1376 google.golang.org/grpc.(*Server).handleStream@C:/Users/Administrator/go/pkg/mod/google.golang.org/[email protected]/server.go:1753 google.golang.org/grpc.(*Server).serveStreams.func1.1@C:/Users/Administrator/go/pkg/mod/google.golang.org/[email protected]/server.go:998 runtime.goexit@C:/Program Files/Go/src/runtime/asm_amd64.s:1650 Error: not found Time taken: 0.00117s
