Looks like this parameter HAS to be a .csv file for your script to
work correctly. In this case you should be using a
QgsProcessingParameterFile, with a csv extension, as your parameter,
not a QgsProcessingParameterFeatureSource (which could be any type of
layer, including non-disk based formats like memory layers or postgis
databases).
If you swap to a QgsProcessingParameterFile then parameterAsFile
should work as expected.
