Copy layers between webmaps not working.

Why is this not working for copy layers from one webmap to another?

map1 = gis.content.get(<itemID_1>) map2 = gis.content.get(<itemID_2>) webmap1 = WebMap(map1) webmap2 = WebMap(map2) layer = webmap2.definition.operationalLayers[0] webmap1.definition.operationalLayers.append(layer) webmap1.update()

I get no error messages, but there is no alteration on webmap1 as well.

It add the layer to the webmap1 when i check for it before webmap1.update(), but this update has no effect.

Hi @HenriqueJoner

There might be a couple of ways to do this but the below has worked successfully.

from arcgis import GIS agol = GIS("home") map1 = agol.content.get("***wm1_id***") map2 = agol.content.get("***wm2_id***") map1_data = map1.get_data() map2_data = map2.get_data() ## the layer index to copy ## index 0 is the bottom layer and those above ## increment by 1 for each layer lyr2copy = map2_data['operationalLayers'][0] ## add the JSON or the layer to the JSON of the other ## WebMap operationalLayers map1_data['operationalLayers'] = map1_data['operationalLayers'] + [lyr2copy] ## Update the data for the map that the layer was coppied to item_properties = {"text":map1_data} map1.update(item_properties=item_properties)
