The same bug also exists in turf-interpolate.

var pointList = [];
for(let i=0;i<180;i++){
for(let j=0;j<360;j++){
let point = turf.point([-180+j1,90-i1]);
point.properties.solRad = Math.random() * 10;
pointList.push(point)
}}
console.log(turf.featureCollection(pointList))
var options = {gridType: 'points', property: 'solRad', units: 'degrees'};
var grid = turf.interpolate(turf.featureCollection(pointList), 1, options);
console.log(grid)

Such code result is:
{type: 'FeatureCollection', features: Array(64800)} {type: 'FeatureCollection', features: Array(179)}

It only interpolate -0.5 longitude.

However, if the longitude and latitude are set as -180-0 and 90-0 (1/4 size of global), it works:
{type: 'FeatureCollection', features: Array(16200)} {type: 'FeatureCollection', features: Array(15842)}

Thanks~
