In the issue Alessandro pointed to: QgsVectorLayerUtils.createFeature
https://qgis.org/pyqgis/master/core/QgsVectorLayerUtils.html?highlight=qgsvectorlayerutils#qgis.core.QgsVectorLayerUtils.createFeature THAT one takes the expression context into account! So: Given an editable layer 'layer' and a valid 'geom": feat = QgsVectorLayerUtils.createFeature(layer, geom, {}, layer.createExpressionContext() ) iface.openFeatureForm(layer, feat) works!!
