Any help with the error message below would be appreciated. 

Thanks,

Just some additional info.  There really is no extension for an ESRI format grid so this error message is hard to understand.

I see two 'clips':

Clip—Help | ArcGIS Desktop  where the syntax is arcpy.Clip_analysis(.....)

and

Clip—Help | ArcGIS Desktop  where the syntax is arcpy.Clip_management(.....)

Where is arcpy.Managemnet.Clip()  ?

That should just about do it....

see below... it should be the clip in analysis

What is this value?

outrasterpath + featureClass

You should be using Clip in the Analysis toolbox

Clip—Help | ArcGIS Desktop  same in arcmap or pro

Clip in management is for grids

It seems they're trying to perform raster clip, so this (i.e. management clip) is the correct tool.

Yes, clip management is the right one, outrasterpath is defined below:

# out path to clipped rasters
outrasterpath = r"S:/General-Offices-GO-Trans/SLR-Mapping/GIS_Projects_2018/Smart_T_Line_Model/geodata/TEST_RASTERCLIP.gdb/"

Script is still not working.

from your script all I see is featureclasses,  Where is the raster coming from?

Something is missing.  Is the raster defined somewhere else?

featureClassList = arcpy.ListFeatureClasses()
for featureClass in featureClassList:
    for row in arcpy.da.SearchCursor(featureClass,'SHAPE@'):
        arcpy.management.Clip(raster, row[0].extent, o

can you provide what is needed for your raster clip, like... raster, outrasterpath. 

raster, row[0].extent, outrasterpath + featureClass, featureClass, -3.402823e+38, "ClippingGeometry", "MAINTAIN_EXTENT"

also, you aren't specifying any file name for the raster so you will end up with esri grids which I am not sure if your nodata value minimum  (-3.402823e+38) is supported... maybe check that as well

Yes, hoping for ESRI grids as output.  Not sure where to check on the nodata value minimum?
