Strange error when using leaflet-lasso with leaflet-curve

[Eric]

I have a code pen demonstrating the issue at https://codepen.io/ericg_off/pen/JjLGWLw

I am using:

• https://unpkg.com/leaflet@1.8.0/dist/leaflet.js
• https://unpkg.com/leaflet-lasso@2.2.8/dist/leaflet-lasso.umd.min.js
• https://unpkg.com/@elfalem/leaflet-curve@0.9.1/dist/leaflet.curve.js

To reproduce:

1. Click on the lasso control in the upper right corner.
2. Draw a lasso around the markers

The following error will appear:

t-spatial.esm.js:522 Uncaught TypeError: Cannot read properties of undefined (reading 'type')
    at t (t-spatial.esm.js:522:15)
    at calc.ts:6:20
    at Array.filter (<anonymous>)
    at U (calc.ts:58:35)
    at e.finish (lasso-handler.ts:189:34)
    at e.onDocumentMouseUp (lasso-handler.ts:151:14)

I am not sure if the actual bug is in the lasso code or in the curve code.

As confirmed by the leaflet-lasso author, the bug is on their end.
