Candles ticks history with start parameter not working

Ariakas

Hi. I'm using websocket connection via

wss://ws.binaryws.com/websockets/v3?app_id=<my_app_id>

According to offical docs I can request history starting from some epoch but socket doesn't respond me anything. Here's my websocket message:

{
"ticks_history" : "frxGBPJPY",
"count" : 14,
//"end" : 1690270200,
"start" : 1690258500,
"style" : "candles",
"granularity" : 900
}

By the way history ending at some epoch works correct. What am I doing wrong?
