I'm converting Python standalone scripts from Desktop (10.6.1)  to Pro (2.3.2).  I can add a raster to an open Pro project file interactively by right clicking on the raster in the Catalog and choosing "Add to Current Map".  I would like to do this in a script and have tried two ways (one commented out below):

inRas = '<projectDir>/Risks/riskv0'
outAPRX = '<projectDir>/Reports/riskv0/riskv0.aprx'
templateFile = '<projectDir>/MapTemplates/risksTemplate/risksTemplate.aprx'
aprx = arcpy.mp.ArcGISProject(templateFile)
map = aprx.listMaps()[0]
map.addDataFromPath(inRas)
#refLyr = map.listLayers()[1]
#map.insertLayer(refLyr, inRas, "AFTER")
aprx.saveACopy(outAPRX)
del aprx‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

When I use addDataFromPath, I receive a RuntimeError for line 6 with no further information.

The listLayers/insertLayer approach results in a ValueErr at line 8 for the inRas file.

I would be grateful for any advice on adding a raster to a map in Pro.

I have developed a workaround that writes the raster to a layer file and retrieves this version for the map insertion:

inRas = '<projectDir>/Risks/riskv0'
outAPRX = '<projectDir>/Reports/riskv0/riskv0.aprx'
templateFile = '<projectDir>/MapTemplates/risksTemplate/risksTemplate.aprx'
aprx = arcpy.mp.ArcGISProject(templateFile)
map = aprx.listMaps()[0]
refLyr = map.listLayers()[1]
arcpy.MakeRasterLayer_management(inRas, "insertRas")
arcpy.SaveToLayerFile_management("insertRas", '<tempDir>/insertRas.lyrx')
insertLyr = arcpy.mp.LayerFile('<tempDir>/insertRas.lyrx')
map.insertLayer(refLyr, insertLyr, "AFTER")
aprx.saveACopy(outAPRX)
del aprx‍‍‍‍‍‍‍‍‍‍‍‍

 I trust it doesn't have to be this complicated!  Is there a way to work with the raster without writing/reading the temporary file?
