TypeError: "curve.trace is not a function"

[JensC]

First of all, thanks for implementing the helpful trace method. In a react app I wanted to use the new method and I got the error mentioned in the title. Drawing the curve works just fine.

Here is the used code snippet

          if (this.map != null) {
            let curve = L.curve(path,
              this.props.polylineOptions).addTo(this.map);
            const points = curve.trace([0.25, 0.5, 0.75]);
            console.log('Curve trace *****', points)
//          this.addArrowDecorators(points);
          }

I am using leaflet 1.1.0 and the newest (0.5) Leaflet.curve. Any idea what is going wrong?

From the code snippet you provide, I would expect it to work. I'm not sure what could be wrong.

What do you get if you debug the following?

console.log(curve)
console.log(curve.trace)

I faced the same issue
console.log(curve.trace) returns :
ƒ (t){
t = t.filter(function(element){
return element >= 0 && element <= 1;
});
var point, curCommand, curStartPoint, curEndPoint;
var p1, p2, p3; ...

console.log(curve) returns:

@JensC @khetamHamad An outdated version of the plugin was published as 0.5.0. This is why there were errors with the trace function not being recognized. An accurate package has been published as 0.5.2.
