sending notifications to Huawei does not work via gRPC

[vanohaker]

My code:

func (g *GrpcGorush) SendToHuaweiAndroid(body Notification, index int, uuids []string) {
	request, err := g.gorushClient.Send(context.Background(), &proto.NotificationRequest{
		Platform: 3,
		Tokens:   uuids,
		// Message:     body.Annotations,
		// Title: body.Title,
		// Priority: proto.NotificationRequest_NORMAL,
		// Image:       body.ImageMedia,
		Data: &structpb.Struct{
			Fields: map[string]*structpb.Value{
				"title": {
					Kind: &structpb.Value_StringValue{StringValue: body.Title},
				},
				"href": {
					Kind: &structpb.Value_StringValue{StringValue: body.NotifiHref},
				},
				"image": {
					Kind: &structpb.Value_StringValue{StringValue: body.ImageMedia},
				},
			},
		},
	})
	if err != nil {
		g.logger.Info().Int("Chunk", index).Err(err)
	}
	if request != nil {
		g.logger.Info().Int("Chunk", index).Msgf("Success: %t", request.Success)
		g.logger.Info().Int("Chunk", index).Msgf("Count: %d", request.Counts)
	}
}

Server log:

{"level":"debug","msg":"Start push notification for Huawei","time":"2024-04-26T10:58:22Z"}
{"level":"debug","msg":"Default message is {\"validate_only\":false,\"message\":{\"android\":{\"urgency\":\"NORMAL\",\"ttl\":\"86400s\"},\"token\":[\"IQAAAACy0sAbAACa6SbyCxYQWR2iMqGJMv....\"]}}","time":"2024-04-26T10:58:22Z"}
{"level":"debug","msg":"Huawei Send Notification is failed! Code: 80100003","time":"2024-04-26T10:58:22Z"}

If I send a message via web api then everything is sent correctly

curl -X POST -H 'Content-Type: application/json' https://push.dev/api/push -d @payload_huawei.json

payload_huawei.json

{
  "notifications": [
    {
      "tokens": ["IQAAAACy0sAbAACa6SbyCxYQWR2iMqGJMv..."],
      "platform": 3,
      "huawei_data": "{'title': 'title text', 'href': 'app_name://n/2823280/?from=push', 'image': 'https://host/home/n/2024/20240419/a.jpg'}"
    }
  ]
}

Server log:

{"level":"debug","msg":"Start push notification for Huawei","time":"2024-04-26T11:04:20Z"}
{"level":"debug","msg":"Default message is {\"validate_only\":false,\"message\":{\"data\":\"{'title': 'title text', 'href': 'app_name://n/2823280/?from=push', 'image': 'https://host/home/n/2024/20240419/a.jpg'}\",\"android\":{\"urgency\":\"NORMAL\",\"ttl\":\"86400s\"},\"token\":[\"IQAAAACy0sAbAACa6SbyCxYQWR2iMqGJMv...\"]}}","time":"2024-04-26T11:04:20Z"}
{"level":"debug","msg":"Huwaei Send Notification is completed successfully!","time":"2024-04-26T11:04:20Z"}

The NotificationRequest structure does not have a hoawei_data field. I can pass *structpb.Struct as Data, and not string as in huawei_data.
How to correctly pass a string to Data or is this some kind of bug in the implementation of the rpc server?

I will take it.
