Gee编程，JavaScript报错

代码：

var dataset = ee.ImageCollection('USGS/NLCD_RELEASES/2019_REL/NLCD');
var collection01 = imageCollection.filterDate('2018-05')
    .filterBounds(table)
    .first()
    .select("landcover");

var collection1 = collection01.clipToCollection(table);
var visParams = {bands:['landcover'],gain:0.3};
Map.centerObject(table);
Map.addLayer(table,{color:'FF0000'},'table');
Map.addLayer(collection1,visParams,'collection1');

Export.image.toDrive({
  image: collection1.select(['landcover']),
  description: 'lc201805',
  scale: 30,
  region:table
  
});

报错：

img

你在region后面加上input参数试试 input:""
