How Can I fix this runtime error from addAllValues()?

Hello,

I am having trouble adding all values to layers symbology. If I use 'addAllValues()' by itself on one layer it works fine. However, when I create a list and do this en masse I get the following error:

Traceback (most recent call last): File "\\PDCCITRDSGIS02\Projects_3\PGE\00129_21_Kleinfelder_VegManagement\Tools\Scripts\Make_Figure2_experimental.py", line 77, in <module> hab_lyr.symbology.addAllValues() File "C:\Program Files (x86)\ArcGIS\Desktop10.8\ArcPy\arcpy\_mapping.py", line 1387, in addAllValues return convertArcObjectToPythonObject(self._arc_object.addAllValues(*gp_fixargs((), True))) RuntimeError

An excerpt of my code is below. It is strange, because in my full code, I set a def query on hab_lyr with no problem.

for lyr in layers_list: print "Updating Work Area and Buffer Data Sources..." hab_lyr = arcpy.mapping.ListLayers(mxd, lyr)[0] if hab_lyr.symbologyType == "UNIQUE_VALUES": hab_lyr.symbology.addAllValues()

Add some print statements before the hab_lyr.symbology.addAllValues() so you know which layer is causing that error. I tried it on a couple of my datasets and it didn't throw that error so you'll have to do some more debugging to narrow the issue down.

print 'changing: {}'.format(hab_lyr.name)
