Create candlestick series not working in v 3.1.2

[nakcyber]

Hi, lightweight-charts team
I try to create candlestick series in lightweight-charts v.3.1.2,
I found an error in console Uncaught Error: Value is null

Lightweight Charts Version: 3.1.2

Actual behavior: Show Uncaught Error: Value is null;

Expected behavior: Don't show Uncaught Error: Value is null;

You have 2 points with the same time, that's the reason.
