I'm getting this error when trying to run project on azure windows server but It's working fine on Ubuntu machine and My Local Windows machine. I have deploy flask project on Apache with mod_wsgi server.
I have already installed the all the required dependencies.

Please help me to resolve the issue. It would be very helpful for me.
Are you sure that azure.storage is installed on the machine?
Please install it before you run your project:
script: pip install azure-storage
Try pip list to see what all modules are installed on your machine.
Also, see that, the version which is used by your code, is installed on your machine.

I'm experimenting and working on a Flask webpage what's gonna use some data from MySQL database and after a little coding I got internal server error and I don't know why.
After several days I cant work out the problem what can I do for it to work?
I'm using Python3, the server where is hosted is Ubuntu system and I can reach the site via LAN right now with the servers LAN domain (server's name) name that I host via Hyper-V cause I don't have a spare PC for that with Ubuntu on it.
The weird part abut it that when I test it locally on my laptop I wont get the 500 Error only if I want to connect the page what's hosted on the server virtual machine.
Because I don't know where is the problem I uploaded most of the files to GitHub, this gonna be changed of course and later deleted for security reasons but now its easier.

Do not download the module I mistook content_management as pip module. you can uninstall the module pip uninstall contentful_management
The error comes because you are importing module in init.py.
try this:
from name_of_the_parent_directory import content_management
You an try using
from . import content_management
name_of_the_parent_directory - means the parent directory, in your github it will be webpage.
I have a flask application running on apache server in the Linux box(ec2 instance), which calls the python script that does the work of moving the files from s3 to snowflake. The script works fine if executed directly. It throws the below error for the snowflake's ingest python module when trying to host it on apache using virtualhost and mod_wsgi. The module is installed in the default site packages.
Apache server version: 2.4.41
Python Version: 3.7
snowflake: snowflake_connector_python-2.1.3-py3.7-nspkg.pth
OS: AMAZON linux 2
Below is the apache error log, when i try to restart:

It looks like when you're executing this from mod_wsgi, you're using Python 2 instead of Python 3. The error message you see is happening because Snowflake's simple ingest manager uses type hints (via the typing module), which are not available in Python 2.
Here's a simple fragment that fails with the same error in Python 2 but succeeds in Python 3:
from typing import Text
def foo(bar: Text):
print(bar)
foo('huh')
I am making use of python3 for building the application

Your config file should look like this:

SECRET_KEY = '<your-very-secret-key>'
Then you can do:
app = Flask(__name__)

I am currently trying to publish via ZIP my django app to an AWS elasticbeanstalk.
As I have a local and online development enviroment I would like to make use of the environ variables, that are used anyways by AWS.
For my development environments I am already using virtualenv. Apache runs with wsgi enabled and is supposed to use such environments. Unfortunately, it does not know the environ that I have set in the bin/activate.
Django throws a 500 error, since it cannot connect to the database as it does not have access to the environ vars:
1:53.862779 2015] [wsgi:error] [pid 20639] [remote 127.0.0.1:51896] KeyError: 'RDS_DB_NAME'
If I activate my env and look into the env vars:
(myenv)[bs#debian-gohan:]/var/www/vhosts/mysite $ env | grep RDS
RDS_HOSTNAME=localhost
... and I get the others as well...
My Apache Vhost is:
<VirtualHost *:80>
WSGIDaemonProcess mysite python-path=/home/bs/envs/myenv/bin/python2.7:/home/bs/envs/myenv/lib/python2.7/site-packages
WSGIProcessGroup mysite
WSGIScriptAlias / /var/www/vhosts/main-page/mysite/wsgi.py
Does anyone have an idea why the environ vars are not seen by the apache ?
EDIT 1:
I have tried to use SetEnv in the Apache config, like this:
SetEnv RDS_HOSTNAME "localhost"
Unfortunately, this did not work. I then removed the ProcessGroup and only used a simple WSGIPythonPath. That did not work either.
The error in the apache log remains the same:
