[Python] How to get the Exception (Message and StackStrace) of a Python Azure Function

With the following AzureFunction (config.nonsense is not defined):

import azure.functions as func
import logging
import zsbiconfig
# import triggerfunc

app = func.FunctionApp()

@app.timer_trigger(schedule="0 */1 * * * *", arg_name="myTimer", run_on_startup=True,
use_monitor=False)
def zsdbi(myTimer: func.TimerRequest) -> None:

if myTimer.past_due:
logging.info('The timer is past due!')

logging.info('27 Python timer trigger function executed.')

config = zsbiconfig.MyConfig(azure=True)
print('config.ftp_host:', config.ftp_host)
print('config.ftp_username:', config.ftp_username)
print('config.ftp_password:', config.ftp_password)
print('config.ftp_nonsense:', config.nonsense) # I will produce a Exception

# err = triggerfunc.triggerfunc(config)

return



I produce the following Error (Shown here is the Monitoring LogStream):

2025-01-17T13:45:00Z [Verbose] Sending invocation id: 'f65a61af-e12a-4bfe-8bd2-7e30fee4eede

I cannot figure our how to get the full Stacktrace and ErrorMessage of this Exception in Application Insights. Here is my host.json :

"version": "2.0",
"logging": {
"applicationInsights": {
"samplingSettings": {
"isEnabled": true,
"excludedTypes": "Request"
}
}
},
"extensionBundle": {
"id": "Microsoft.Azure.Functions.ExtensionBundle",
"version": "[4.*, 5.0.0)"
}
}



Edit 1 zsbiconfig.py

import os
# from azure.identity import DefaultAzureCredential
# from azure.keyvault.secrets import SecretClient

class MyConfig:

def __init__(self, ftp_host=None, ftp_username=None, ftp_password=None,
sharepoint_url=None, sharepoint_clientid=None, sharepoint_clientsecret=None, azure=False):

self._ftp_host = ftp_host
self._ftp_username = ftp_username
self._ftp_password = ftp_password
self._sharepoint_url = sharepoint_url
self._sharepoint_clientid = sharepoint_clientid
self._sharepoint_clientsecret = sharepoint_clientsecret

self._env_ftp_host = os.getenv('FTP_HOST')
