Compile Error using JsonVariant

Created by: tbnobody

I had the following code running on a ESP8266 using the Arduino Framework:

	StaticJsonBuffer<1024> jsonBuffer;
	JsonObject& root = jsonBuffer.parseObject(json);
	JsonArray& data = root[F("button")];

	uint8_t cnt = 0;

	for (auto dataobj : data) {
		config.Button_Config[cnt].animation = dataobj[F("animation")].as<uint>();
		config.Button_Config[cnt].color = StripeAnimation.ConvertStringToColor(dataobj[F("color")].as<String>());

		cnt++;

		if (cnt > MAX_BUTTON_CONFIG) {
			break;
		}
	}

This code worked perfectly including commit 11432253 and does not work with commit 8499f0b9

I get the following error message:

The line 942 in WebAPI.cpp is the following line (as in the above code snippet): config.Button_Config[cnt].animation = dataobj[F("animation")].as<uint>();

I am not very familiar with templates, but due to the fact it worked in the previous versions it's maybe not wanted to throw an error here?
