I have 2 geojson feature collections in leaflet. One of them is road and the other one is parcels. I want to calculate buffer for road and then intersect this buffer layer with parcels. But when I call buffer function I get an error
Uncaught Error: Invalid unit at Object.module.exports.distanceToDegrees (turf.js:4191) at Object.module.exports [as buffer] (turf.js:652) at index.html?_ijt=k268ek1sbmjfm477kedi24a5t1:5770
Why I get this error? Here is my code example:`
