I'm making my first tool script in QGIS LTR (3.22.8). I'm following the answer given here about multiple layer parameters. I'm using the following code:

        self.tr('Input layers'),

I get this error:

ScriptEditorDialog.py", line 253, in runAlgorithm alg.initAlgorithm() File "", line 105, in initAlgorithm NameError: name 'QgsProcessingParameterMultipleLayers' is not defined

Why is this? I'm using the Python template, and the method QgsProcessingParameterMultipleLayers appears in the autocomplete.

You need to import it first:

from qgis.core import QgsProcessingParameterMultipleLayers
