Objet : Openstreemap pyqgis error


Hello, I have a problem on the development of a python plugin, I'm trying to display the openstreemap map behind layers, only the map is not synchronized with the layers, it can't find it or even the location.
the geographical position of the map does not correspond to that of my layers

Bonjour, j'ai un problème sur le développement d'un plugin en python ,j'essaye de faire afficher la carte openstreemap derrière des layers .Seulement la carte n'est pas synchroniser avec les layers ,elle ce trouve pas ou même endroit.
la position géographique de la carte ne correspond pas à celle de mes couches

#Vlayer is defined above the code / Vlayer est définie au-dessus du code

urlWithParams = 'type=xyz&url=http://a.tile.openstreetmap.org/%7Bz%7D/%7Bx%7D/%7By%7D.png&zmax=19&zmin=0&crs=EPSG3857'
maplayer = QgsRasterLayer(urlWithParams, 'OpenStreetMap', 'wms')
settings = QgsMapSettings()
settings.setLayers([vlayer,maplayer])
settings.setBackgroundColor(QColor(255, 255, 255))
settings.setOutputSize(QSize(800, 690))

settings.setExtent(vlayer.extent())


render = QgsMapRendererParallelJob(settings)

render.start()
render.waitForFinished()

img = render.renderedImage()
img.save(QgsApplication.qgisSettingsDirPath()+"python/plugins/nro_print/img/render.png", "png")
