@QgsVectorFileWriter.writeAsVectorFormat(layer, target_dgn, 'utf8', None, 'DGN', skipAttributeCreation = True)@

@writeAsVectorFormat@ gives code 3 error (ErrCreateLayer) with 'DGN' parameter and exports nothing. When changed into 'dgn', it works.

It's the same in QGIS 3.2.1.
QGIS 3.2.1 gives @(3, 'Creation of layer failed (OGR error: )')@ error.
