I got this error when I called ol.vector.setSource() function with the parameter array contains multiple features. The following is my code:
const holeLayer = new ol.layer.Vector({
source: new ol.source.Vector({
features:
}),
});
const featuresArr = ;
holes.forEach((hole, index) => {
featuresArr.push(new ol.Feature({
geometry: new ol.geom.Circle(hole[0], this.holeRadius / 2, 'XYZ'),
index,
holeNum: index,
selected: index == this.selectedHole,
}));
});
holeLayer.setSource(new ol.source.Vector({
features: featuresArr
}));
I logged out the featuresArr, it is not null.
Anyone has any ideas? Thank you!

Most likely an error or omission in the hole data you are using. Log hole[0] in the loop to check each contains a coordinate array.
