RuntimeError: Object: Error in executing tool - ArcPy - ArcGIS Pro - Apply Symbology from Layer

Question

I have this script to apply the symbology from one layer to many. But when I try and run it, I get the following error: RuntimeError: Object: Error in executing tool

Here is the rest of my code:

import arcpy 
# Reference current project and mapframe. 
relpath = r'C:\arcGIS_Shared\Python'
p = arcpy.mp.ArcGISProject(relpath + r'\CenterHeatMaps.aprx')
m = p.listMaps('Map')[0]
# Layer file symbology to be imported. 
symbology_layer = (r"C:\arcGIS_Shared\Python\Annual2017_CA_ReferenceLyrx.lyrx")
# Layer to receive imported symbology. 
layers = m.listLayers("CA201*") 
for lyr in layers: 
 #Maintain the symbology ranges
# arcpy.update_symbology('MAINTAIN')
 #Apply the symbology
 arcpy.ApplySymbologyFromLayer_management(layers, symbology_layer) 
 #print results
 print(lyr.name)
 count = arcpy.GetMessageCount()
 print (arcpy.GetMessage(count-1))

What am I missing or doing wrong?

• Bera: Do you get a line number in the error message? Dont combine paths using +, instead use os.path.join. Example: os.path.join(r'C:\arcGIS_Shared\Python', r'CenterHeatMaps.aprx')

Answer 1

You're passing in a list of layers: layers to the ApplySymbologyFromLayer tool. instead, you need to pass in just the layer: lyr

for lyr in layers: 
 arcpy.ApplySymbologyFromLayer_management(lyr, symbology_layer)
