dcc.Intervals and "POST /_dash-update-component" when setting animation

Hi Guys,

I’m working on a project with an animated chart where I’m using Dash instead of plotly, to animate it;

The chart:

animation-running700×461 1.91 MB

The problem is that every time that Interval run it do a:
[06/Jul/2020 21:26:03] "POST /_dash-update-component HTTP/1.1" 200 -

For each Interval value it runs two POST requisitions:

Is it correct? how can I avoid it trigger the POST requisition to the server?

THE APPLICATION CODE:
I’m using an Interval that updates my slider

And the slider updated value will be used to plot the correct frame of the figure animation

I would be very grateful if someone can help me doing this task;
