When deploying a python 3.7+ flask or Dash application on IIS using wfastcgi, there are many great tutorials to get a hello work program working such as

Where this process fell apart for me and seeming for other users such as

Can't get dash app run on IIS with flask server

How to deploy python flask application in conda base environment on IIS server?

was when other packages started coming into the mix such as Numpy, Pandas, Dash, Plotly Express, etc.

The error that get throw tended to depend on the package but usually resembled a large block of test that looks like the error bellow starting with Error occurred while reading WSGI handler and featuring things like Dll load failures or missing components.

I deployed a flask app to IIS using FastCGI and WSGI Handler. The steps that I have followed are

1. Created a virtual environment for Python and installed all packages including wfastCGI.
2. Set the Handler mappings and included the FastCGI settings.
3. Assigned the necessary permissions for the folders by adding IIS_IUSRS and IUSR.

Below is the medium link that I followed in terms of the steps. https://medium.com/@dpralay07/deploy-a-python-flask-application-in-iis-server-and-run-on-machine-ip-address-ddb81df8edf3

The folder structure for the code is as shown below with (checkin_env) being the virtual environment.

Fast CGI settings are shown as below with WSGI Handler being checkFlask.app

The web.config file which was generated is here.

When I tried running on Ports 80, 5000 I received a permission error related to System32 which I am totally confused and unsure about. Any thoughts or inputs are highly appreciated. Thank you.

I'm using Google App Engine standard environment to host a python-flask-application and I'm having issues to get the errors to show up in StackDriver Error Reporting. By default Google App Engine should log errors to StackDriver Error Reporting, but it doesn't.

I've had errors before that showed up in StackDriver Error Reporting, but I can't reproduce that. The errors seem to go straight to the Server-Errors section and not to the Application-Errors. But it seems logical to me that both are logged in StackDriver Error Reporting.

I did some debugging in order to get it working using routes /error and /500. The result was the following:

• The errors show up in the Google App Engine overview:
• Both are visible in the logs:
• But nothing shows up in StackDriver Error Reporting:

Would anyone have an idea why this is the case?

UPDATE: I found that using the flask.logger seems to be the problem. Using logging works ok and ends up in StackDriver Error Reporting (except for some formatting issues). Both do end up in the logger though. I am using a logging.StreamHandler to register to flask.logger using addHandler. My best guess is that there is something wrong with the formatting of the logging.StreamHandler. Investigating further.
