I had a Python Flask website that ran fine when I ran the app pool as my own account. When I tried changing this to a service account (which should have permissions), I get the following error
HTTP Error 500.0 - Internal Server Error
The page cannot be displayed because an internal server error has
occurred.
Most likely causes: •IIS received the request; however, an internal
error occurred during the processing of the request. The root cause of
this error depends on which module handles the request and what was
happening in the worker process when this error occurred. •IIS was not
able to access the web.config file for the Web site or application.
This can occur if the NTFS permissions are set incorrectly. •IIS was
not able to process configuration for the Web site or application.
•The authenticated user does not have permission to use this DLL. •The
request is mapped to a managed handler but the .NET Extensibility
Feature is not installed.

If I change it back to run as my own account, it works. Any thoughts?
FYI after some tinkering, I changed the app pool to run with Managed Pipeline mode of "Classic" instead of "Integrated" and it worked.

Django: 4.0.6
Smartsheet Python SDK: 2.105.1
Ngrok: 3.0.6
I have a Django server running on localhost, forwarded my localhost through Ngrok, have setup a callback route for accepting/responding to the Smartsheet-Hook-Challenge, and created a webhook instance using Python SDK. However, when I try to enable my webhook by running the following (documented here):
Webhook = smartsheet_client.Webhooks.update_webhook(webhook_id,smartsheet_client.models.Webhook({'enabled': True}))
Ngrok immediately returns 502 bad gateway, and my webhook instance's disabledDetails attribute becomes Request returned HTTP status code 502 (ref id: wtegm9). And I have no clue what's the cause of this 502.
PS: While I'm writing this question, I was able to successfully enable my webhook using cURL command, so I can go ahead and start working. But enabling the same webhook instance with update_webhook python method still gives 502. Since updating webhook with cURL worked, could it be a bug in the Python SDK method itself?
I would suspect that an issue with Ngrok is causing the 502 error and not a problem with the Smartsheet SDK. A Google search for http 502 bad gateway ngrok returns lots of info about 502 errors with Ngrok, including this Stack Overflow post which contains multiple widely approved answers:
Ngrok errors '502 bad gateway'
I'd start there, if I were you.
I have set up a Python flask through IIS. I have set up IIS and wfastcgi. I have verified below -
Install IIS and CGI
Install wfastcgi
Created webconfig file
Configure IIS directories and permissions
When i try to URL I am seeing below -
HTTP Error 500.0 - Internal Server Error
An unknown FastCGI error occurred
Most likely causes:
IIS received the request; however, an internal error occurred during the processing of the request. The root cause of this error depends on which module handles the request and what was happening in the worker process when this error occurred.
IIS was not able to access the web.config file for the Web site or application. This can occur if the NTFS permissions are set incorrectly.
IIS was not able to process configuration for the Web site or application.
The authenticated user does not have permission to use this DLL.
The request is mapped to a managed handler but the .NET Extensibility Feature is not installed.
Things you can try:
Ensure that the NTFS permissions for the web.config file are correct and allow access to the Web server's machine account.
Check the event logs to see if any additional information was logged.
Verify the permissions for the DLL.
Install the .NET Extensibility feature if the request is mapped to a managed handler.

What I am missing please help
When I try to create a Python file (.py) in my Django application, I get an error 500. The file is created, and the code isn't the problem. I can create a text file or any other format. It would need to be a Python file because I need it for further steps.
I am using Windows 10 and running the Django application on IIS. Windows, IIS and Django are all up-to-date.
I already tried to add permission to the folder I will edit. I tested around with some other settings but haven't figured out the problem yet. I think it should be something with permission of IIS or Django.
This is my error message:

I was able to solve my problem. I switch from IIS to Apache which didnt had any problem with creating a .py file anymore. After that I got an empty models file. The only thing left to do was to add in the absolute path python in the os.system(command).
Now everything works fine.
you need to check some below settings:
1)you enable iis CGI feature.
2)ensure pip and setup tools are fully upgraded:
python -m pip install pip --upgrade && pip install setuptools --upgrade
3)install the virtualenv tool:
pip install virtualenv
4)Activate the virtualenv so all our commands affect this interpreter.
C:\inetpub\wwwroot\mydjangoproject\> venv\scripts\activate
5)Configured the WFast CGI in iis.
6)"d:\django\virtualenv0\" path has iis_iusrs and iusr full control permission.
7)check iis application pool identity which server Django project.
for more detail, you could refer this link.
and please share your web.config file for more detail about the issue.
I have written a code in python using youtube data API v3 where I am listing playlists created by a user. I have followed the code suggested by youtube API it runs well in local machine but when I deployed the same code on the server, It runs till authentication but after OAuth, it displays Internal server error in the browser instead of the result.
is there any major changes that I am missing. Please help me with the issue.
My code in not running after oauth2callback function runs.
I solved the error,
I was deploying without a secure connection and that was raising an error. also redirect URL must be 'https' that was another problem.
I am running a Django REST API on Google Kubernetes Engine, using Gunicorn for my WSGI server. When my application encounters a 500 server error, the Python stack trace is not showing up in the GCP Logging console (in the "GKE Container" resource). In a different Django project of mine which uses Daphne for the ASGI/WSGI server, this traceback is being properly logged. Even more strange, the Gunicorn application has properly logged errors before, just a few weeks ago. Those errors appear in the Error Reporting console as well.
To be clear, this is the type of information that I would like to see in the GCP logs:
Internal Server Error: /v1/user/errant-endpoint
Traceback (most recent call last):
File "/path/to/python3.6/site-packages/django/core/handlers/exception.py", line 34, in inner
response = get_response(request)
...
File "/path/to/project/file.py", line 176, in my_file
print(test)
NameError: name 'test' is not defined
For the Gunicorn project, some of the Python tracebacks are logged, like this one when Gunicorn is started:
/usr/local/lib/python3.6/site-packages/django/db/models/fields/__init__.py:1421: RuntimeWarning: DateTimeField User.last_login received a naive datetime (2019-02-04 05:49:47.530648) while time zone support is active.
With 500 errors, however, only the HTTP info is logged:
[04/Feb/2019:06:03:58 +0000] "POST /v1/errant-endpoint HTTP/1.1" 500
I've looked up the resources for setting up Stackdriver Logging and Stackdriver Error Reporting, but neither of these seem to apply because 1) that only appears to work when you want to explicitly log your errors (as in client.report_exception()), and 2) Error Reporting has caught previous errors without my setting up, so it seems to be possible without having to install those client libraries.
There are so many variables at play here that I'm not sure where to start. I may not have provided enough information here in order to properly diagnose this (docker setup, kubernetes configuration, etc.), but I figured I may be misunderstanding something fundamental about this process, and that someone could be so kind as to enlighten me.
EDIT:
I found in the GKE documentation how to ensure that the Stackdriver logging is enabled for my cluster. Still no luck.
UPDATE (partial solution):
I set DEBUG = True in settings.py, which prompted the errors to start being logged in Stackdriver Logging and Error Reporting. I've gone ahead and done this for my canary environment, but it's less than ideal, since it exposes some of my backend code. Still not sure why this works for my other GCP project without running in debug mode.
