I have just started using PyQGIS and need to loop over parcels in a vector layer to clip a raster layer.

For each parcel, I want to generate a .tif file with the feature.id() in the filename. I will also be saving the attributes in a separate .csv/.txt file by the same name. Because of this, I can't run the script using the iterator in the GUI.

This is what I have come up with thus far:



    raster = 'C:/Datasets/orthophotos/OMWRGB21VL_K14_K15/OMWRGB21_VL_K14_K15.tif'
    Lbgbrprc = 'C:/Datasets/Landbouwgebruikspercelen/Landbouwgebruikspercelen_2020/Shapefile/Lbgbrprc20_SintNiklaas.shp'
    Lbgbrprc = QgsVectorLayer(Lbgbrprc, 'landbouw', 'ogr')
    
    params = \
    { 'ALPHA_BAND' : False, 'CROP_TO_CUTLINE' : True, \
    'DATA_TYPE' : 0, 'EXTRA' : '', \
    'INPUT' : raster, \
    'KEEP_RESOLUTION' : False, \
    'MULTITHREADING' : False, 'NODATA' : None, 'OPTIONS' : '', \
    'SET_RESOLUTION' : False, 'SOURCE_CRS' : QgsCoordinateReferenceSystem('EPSG:31370'), 'TARGET_CRS' : QgsCoordinateReferenceSystem('EPSG:31370'), 'X_RESOLUTION' : None,'Y_RESOLUTION' : None }
    
    
    request = QgsFeatureRequest()
    for feature in Lbgbrprc.getFeatures(request):
        if int(feature.id()) < 5:
            print(type(feature)) # <class 'qgis._core.QgsFeature'>
            params['MASK'] = feature
            params['OUTPUT'] = 'C:/Output/ortho_Lbgbrprc/{}.tif'.format(feature.id())
            
            processing.run("gdal:cliprasterbymasklayer", params)
            

This is the error I get:

    Could not load source layer for MASK: invalid value

I think the issue is that the 'MASK' parameter needs to be a `QgsVectorLayer` not a `QgsFeature`, which is what "feature" is now. How do I go about this?
