Lottie Number Counter glitch

[JoshSt]

I made an animation for a client and they wanted it to be a lottie json to implement into their app. I had some problems with the lottie exports but was able to fix all of them except for the number counter.

I tried the counter expression with a slider and as pure javascript but got the same result with both ways.

Does someone know how to fix this lottie export issue?

The file as a video and a screencapture of the lottie are in the attachment.

Thanks in advance,

Josh

And what is the actual code? It seems you assume that stuff like linear(), ease() or whatever exist in generic JS when you may need to implement your own code or some sort of node.js third-party library.

I was browsing some web discussions about number counters with lottie and it seemed to work for some people so I guessed it would work with simple javascript.

This is the code I'm using;

var startValue = 50; // Starting value
var endValue = 100; // Ending value
var duration = 1; // Duration in seconds
var delay = 3.675; // Delay in seconds
var currentValue = Math.round(linear(Math.max(time - delay, 0), 0, duration, startValue, endValue));
currentValue + "%";
