Protobuf消息没有实现protoreflect.ProtoMessage（ProtoReflect方法有指针接收器）

message mintrecord {
    ...
    google.protobuf.any data = 11;
    ...
}

data, err := anypb.new(protobuf.lootcrateprize{
    items: &protobuf.inventory{items: items},
    roll:  fmt.sprintf("%f", roll),
})
if err != nil {
    log.println("[lootbox] err: error marshalling lootcrate prize data into mintrec", err)
} else {
    mintrecordproto.data = data
}

cannot use protobuf.lootcrateprize{…} (value of type protobuf.lootcrateprize) as type protoreflect.protomessage in argument to anypb.new:
    protobuf.lootcrateprize does not implement protoreflect.protomessage (protoreflect method has pointer receiver)

syntax = "proto3";

package protobuf;
option go_package = "protobuf/";

import "protobuf/inventory.proto";
import "protobuf/flowerdbservice.proto";

message LootcratePrize {
    Inventory items = 1;
    repeated NFT flowers = 2;
    string roll = 3;
}

data, err := anypb.New(&protobuf.LootcratePrize{
    Items: &protobuf.Inventory{Items: items},
    Roll:  fmt.Sprintf("%f", roll),
})
