Error while trying to export gee data and display appears (Error code: 3) - google-earth-engine

Question

when I export the GEE data it appears
Error: Image.clipToBoundsAndScale, argument 'input': Invalid type.
Expected type: Image. Actual type: FeatureCollection.
(Error code: 3)
can you help me solve it
following is the script code
var maskL8 = function(image) {
var qa = image.select('BQA');
var mask = qa.bitwiseAnd(1 << 4).eq(0);
return image.updateMask(mask);
}
var composite = ee.ImageCollection('LANDSAT/LC08/C01/T1_TOA')
.filterDate('2021-01-01', '2021-12-31')
.filterBounds(geometry)
.map(maskL8)
.median().clip(geometry);
//visualisasi citra

var classifier = ee.Classifier.smileCart().train({

inputProperties: bands
});
var classified = composite.select(bands).classify(classifier);
Map.addLayer(classified,
{min: 0, max: 7, palette:['darkgreen','blue','red','darkblue','green','orange','yellow', 'brown']},
'classification');
//Klasifikasi
var uji_aoi = uji_akurasi_vegetasi.merge(uji_akurasi_badanair).merge(uji_akurasi_lahanterbangun).merge(uji_akurasi_tegalan)

var validasi = classified.sampleRegions({

scale: 30,
});
print(validasi);
var akurasi = validasi.errorMatrix('lc', 'classification');
print('Confusion matrix', akurasi);
print('Overall accuracy: ', akurasi.accuracy());
var class_areas = ee.Image.pixelArea().divide(1000*1000).addBands(classified)

for(var a = 0; a < 8; a++){
panel.add(list_legend(color[a], lc_class[a]))
}
Map.add(panel)
// Export the image, specifying the CRS, transform, and region.
Export.image.toDrive({
image: geometry,
description: 'imageToDriveExample_transform',

});
I try to export data but the result is always the same. Is there an error in this code?
