You cannot use getFeatures() like this: it returns a feature iterator
which you need to use for accessing features - the state of iteration
over features is not held there, not in the provider. This is the
easiest way to use it:

for feature in vproviderA.getFeatures():
  type = feature["type"]
  # do something with type
