问题

自定义feature 时

let feature = {
                      type: 'Feature',
                      properties: { levelValue: itemLevelValue },
                      geometry: searchWithin.geometry
                    }
                    gridFeatures.features.push(feature)

## 应该这样定义features
```javascript
// 
 let gridFeatures = {
          type: 'FeatureCollection',
          name: 'gridFeatures',
          features: [] as any[]
        };
