Print task causes severe ArcGIS for Server log messages

NhuMai — Sun, 12 Dec 2021 16:42:29 GMT

I've tried to implement a print widget using the print task very closely following this tutorial. However, it is very slow (~60 seconds to export an A3 pdf with default dpi) and I notice the following severe ArcGIS for Server logs:

Has anyone seen this type of vague log?

The python script used:


import arcpy
import os
import uuid

# The template location in the registered folder (as UNC path)
templatePath = '//ourserver/ourtemplatepath

# Input WebMap json
Web_Map_as_JSON = arcpy.GetParameterAsText(0)

# Format for output
Format = arcpy.GetParameterAsText(1)
if Format == '#' or not Format:
 Format = "PDF"

# Input Layout template
Layout_Template = arcpy.GetParameterAsText(2)
if Layout_Template == '#' or not Layout_Template:
 Layout_Template = "A3 Paysage"

# Extra parameter - georef_info
Georef_info = arcpy.GetParameterAsText(3)
if Georef_info == '#' or not Georef_info:
 Georef_info = "False"

# Convert Georef_info string to boolean
if Georef_info.lower() == 'false':
 Georef_info_bol = False
elif Georef_info.lower() == 'true':
 Georef_info_bol = True

# Get the requested map document
templateMxd = os.path.join(templatePath, Layout_Template + '.mxd')

# Convert the WebMap to a map document
result = arcpy.mapping.ConvertWebMapToMapDocument(Web_Map_as_JSON, templateMxd)
mxd = result.mapDocument

# Reference the data frame that contains the webmap
# Note: ConvertWebMapToMapDocument renames the active dataframe in the template_mxd to "Webmap"
df = arcpy.mapping.ListDataFrames(mxd, 'Webmap')[0]

# ConvertWebMapToMapDocument renames the active dataframe in the template_mxd to "Webmap".
# Lets rename it to something more meaningful.
df.name = Layout_Template




# Use the uuid module to generate a GUID as part of the output name
# This will ensure a unique output name
output = 'WebMap_{}.{}'.format(str(uuid.uuid1()), Format)
Output_File = os.path.join(arcpy.env.scratchFolder, output)




# Export the WebMap
if Format.lower() == 'pdf':
 arcpy.mapping.ExportToPDF(mxd, Output_File, georef_info=Georef_info_bol)
elif Format.lower() == 'png':
 arcpy.mapping.ExportToPNG(mxd, Output_File)




# Set the output parameter to be the output file of the server job
arcpy.SetParameterAsText(4, Output_File)




# Clean up - delete the map document reference
filePath = mxd.filePath
del mxd, result
os.remove(filePath)

Are you trying to print complex data (vector data with many vertices or imagery)? If so, you might want to try testing on a simpler data set and see how long it takes to print that out in comparison?

It does seem to take less time when removing layers--understandable. However, the end user will need to print about as much as I'm testing, plus, I hadn't noticed this slowness when using the out of the box print widget on the same amount of layers. I think there's something wrong with the gp script, but I'm not sure where to start looking considering the vague error message.

Maybe it has something to do with the setup of your proxy. In my application that was started from an ESRI sample the proxy was:

esriConfig.defaults.io.proxyUrl = /proxy (Shorthand for ESRI's proxy)

which I changed to:

http://"MyServerName"/Proxy/proxy.ashx

Your sample has a proxy:

"http://ourwebserver/Java/proxy.jsp";

Did you use that same proxy when the application was using the out of the box print widget?
