Question

我设法在解决方案中搜索多个错误，但是这次，我找不到它。我完全想尝试标记一个图层。

var vectorSourceMunicipiosAnno = new ol.source.Vector({
  features: (new ol.format.GeoJSON()).readFeatures(GeoJSON_MunicipiosAnno)
});

 var createTextStyleMunicipiosAnno = function(feature) {
 var textAlign = 'center';
 var textBaseline = 'middle';
 var font = feature.get('FontName');
 var size = feature.get('FontSize');
 var text = feature.get('TextString');
 var weight = 'bold';

return new ol.style.Text({
    textAlign: textAlign,
    textBaseline: textBaseline,
    font: weight + ' ' + size + ' ' + font,
    text: text
  });
};

function pointStyleFunctionMunicipiosAnno(feature) {
return new ol.style.Style({
  text: createTextStyleMunicipiosAnno(feature)
});
}

var Layer_MunicipiosAnno = new ol.layer.Vector({
 source: vectorSourceMunicipiosAnno,
 style: pointStyleFunctionMunicipiosAnno,
 zIndex:9
});

我正在使用此代码，它会返回此错误：

TypeError: a.U is not a function

编辑：完整的GeoJSON是这样的：
