   Here is an example of what I'm facing as problem, some others have said to use protojson to unmarshall into a proto message but that is not what I need.

   
   package main
   
   import (
   	"fmt"
   	"time"
   	
   	jsoniter "github.com/json-iterator/go"
   	"google.golang.org/protobuf/runtime/protoimpl"
   	"google.golang.org/protobuf/types/known/timestamppb"
   )
   
   type Test struct {
   	Id        string    `json:"id,omitempty"`
   	ExpiresOn time.Time `json:"expiresOn,omitempty"`
   }
   
   type TestPB struct {
   	state         protoimpl.MessageState
   	sizeCache     protoimpl.SizeCache
   	unknownFields protoimpl.UnknownFields
   	Id            string                 `protobuf:"bytes,1,opt,name=id,proto3" json:"id,omitempty"`
   	ExpiresOn     *timestamppb.Timestamp `protobuf:"bytes,2,opt,name=expiresOn,proto3" json:"expiresOn,omitempty"`
   }
   
   func main() {
   	u := Test{Id: "123", ExpiresOn: time.Now()}
   	
   	b, err := jsoniter.Marshal(u)
   	if err != nil {
   		panic(err)
   	}
   	
   	var m TestPB
   	err = jsoniter.Unmarshal(b, &m)
   	if err != nil {
   		panic(err)
   	}
   	
   	fmt.Printf("PB is %v", m)
   }
