e l'errore è giustificato ;)

INPUT: Input layers

	Parameter type:	QgsProcessingParameterMultipleLayers

	Accepted data types:
		- list[str]: list of layer IDs
		- list[str]: list of layer names
		- list[str]: list of layer sources
		- list[QgsMapLayer]
		- QgsProperty


devi mettere i vari path dentro una lista:

parameters = {'INPUT':
['/home/giacomo/aa/a1.tif;/home/giacomo/aa/a2.tif;/home/giacomo/aa/a10.tif;/home/giacomo/aa/a21.tif'],
\
                        'PCT': False, \
                        'SEPARATE': False, \
                        'NODATA_INPUT': 0, \
                        'NODATA_OUTPUT': 0, \
                        'OPTIONS': "", \
                        'DATA_TYPE': 5, \
                        'OUTPUT': pathOutStack}
