Custom Streaming Tile -moment construction falls back to js Date

Hi Guys

I'm experimenting with creating live tiles directly into a dashboard with streaming datasets. But if i stream a datetime field, the tile is not refreshed and i got this in edge inspector:

"

Deprecation warning: moment construction falls back to js Date. This is discouraged and will be removed in upcoming major release. Please refer to https://github.com/moment/moment/issues/1407 for more info.

I'm using  this in c# to send the value: "DateTime.UtcNow.ToString();";

If i send only the field with the value that i want the tile is refreshed as expected!

I'm doing something that it's not supposed to or is a bug with powerbi?

Thanks

Helder
