Download of a file geodatabase failing when using a script and query

Hi everyone,

I'm trying to download a file geodatabase using a script. The script is taken from the ESRI documentation with minimal changes, basically I'm querying for the required feature layer appending date and time and exporting as a FGDB. The script works as expected by creating the FGDB on AGOL, but when I try and download the FGDB the script fails and fails to export to my local file plan, I can't figure out what is stopping the download, my code is a follows

from arcgis.gis import GIS
import datetime as dt
username = "CSV_GIS_Defects"
gis = GIS('url','username','password', verify_cert=False, proxy_host='proxy', proxy_port=port)
folder_path=r'D:\ArcGisExportData\GeoDatabase'
items = gis.content.search(query="title:CSV_GIS_Defects", item_type="Feature Layer", sort_field='modifed', sort_order='desc')
print(str(len(items)) + " items will be backed up to " + folder_path +". See the list below:")
items

def download_as_fgdb(item_list, backup_location):
for item in item_list:

try:
if 'View Service' in item.typeKeywords:
print(item.title + " is view, not downloading")
else:
print("Downloading " + item.title)
version = dt.datetime.now().strftime("%d_%b_%Y")
print(version)
result = item.export(item.title, "File Geodatabase")
print(result)
result.download(backup_location)
result.delete()
print("Successfully downloaded " + item.title)
except:
print("An error occurred downloading " + item.title)
print("The function has completed")

download_as_fgdb(items, folder_path)

The errors I receive in Jupyter

1 items will be backed up to D:\ArcGisExportData\GeoDatabase. See the list below:
Downloading CSV_GIS_Defects
03_Mar_2022
<Item title:"CSV_GIS_Defects" type:File Geodatabase owner:shaw_b>
An error occurred downloading CSV_GIS_Defects
The function has completed

any help would be greatfully appreciated

Catching the actual error and displaying that might help you find out what's going wrong (or just remove the try/except statements for testing). Possibly, specifying the file name as well in the download parameters might help here?

Hi HuubZwart

Thanks for the response, I removed the try/except block and the error was exposed. I should have thought of it so thanks for the pointer. The error is coming back as an Https proxy timeout, I supply the proxy settings in my connection parameters, they work fine for other scripts my error is

'Tunnel connection failed: 407 Proxy Authentication Required'
