I'm trying to make a wfs layer transparent, but it gives me a mistake, but I can't solve it until now.

this is my code:

uri ='http://gstore.unm.edu/apps/rgis/datasets/6ca5428a-a78c-4c82-8120-da70dc92f2cc/services/ogc/wfs?SERVICE=wfs&VERSION=1.0.0&REQUEST=GetFeature&TYPENAME=tl_2010_35_state10'

wfslayer = QgsVectorLayer(uri, "MEXICO", "WFS")

QgsProject.instance().addMapLayer(wfslayer)

So far everything is correct

renderer = wfslayer.rendererV2()

In this function it gives me the mistake I don't know if it's a problem with the version (QGis 3.16.2) of the program or with the code

it no longer lets me put the rest of the code

symbol = renderer.symbol() symbol.setAlpha(0.5)

Thank you and best regards.
