I have a flask application which was deployed to IBM Bluemix Cloud (which runs on Python 2.7). The application was developed using Python 3 and was made backwards compatible using pasteurize command. The application (after pasteurize) runs as intended on local machine having Python 3, but on the cloud, the instance, when called, raises the following exception:

question_scores is a dictionary having integer keys and float values. After getting the exception, I have additionally put the keys through int method while addition into question_scores, but with no luck as the exception is still raised. So, where am I wrong?

I am using flask to handle image uploads and whenever I upload a jpg, jpeg, or png the program I made is able to handle the upload. However, whenever uploading a .jfif image the program returns the error flask_uploads.UploadNotAllowed. Thanks for any help in advance!
The code the program is having an issue with is:
file_name = photos.save(request.files['photo'])

You are probably using the standard IMAGES set:
https://github.com/jugmac00/flask-reuploaded/blob/f05077b085393dbc607c01b8daff1b3a8b2dbf0b/src/flask_uploads/extensions.py#L29
This set does not allow .jfif files.
However, such a set is really only a Python set, so you can create and use your own, or just update the existing one.
IMAGES.update(".jfif")
I am building a simple “Hello World” using Python, Flask and the Shopify Embedded SDK. Following this tutorial----> https://medium.com/#dernis/shopify-embedded-sdk-with-python-flask-6af197e88c63.
After doing all the work when I go to the link ' https://localhost:5000/shopify/install?shop=khawaja-kaleem-com.myshopify.com ' to install the application to test store it gives me this error. Need to fix it.

You need to specify the API version you wish to use. Set the version before you make any calls. 2020-10 is the default for now.
See the documentation, it explains everything to you.
https://help.shopify.com/en/api/versioning
The ShopifyAPI package specifies the allowed versions in the 'shopify/api_version.py' file. In my case the Shopify platform latest API version is '2022-10' but the latest version allowed by the ShopifyAPI package is '2022-07'.
It seems that the ShopifyAPI package is not always updated quickly after the release of a new API version on the Shopify platform. Try aligning the API version to one of the versions allowed to work around this error.

Please help. Thank you.
I was facing the same problem when I was using session in my app with the following link provided by Flask :
http://127.0.0.1:5000/
Solution: It however perfectly works with http://localhost:5000/
Just replace your local IP address(127.0.0.1) with "localhost".
What I am trying to do is check the subdomain value passed to the route methods just like explained here
Whenever I access the panel blueprint I receive this error: peewee.OperationalError: Connection already open
This is how I initialize the database in my main app file.
flask_db = FlaskDB(app)
database = flask_db.database
The problematic code seems to be
#panel.url_value_preprocessor
def check_client_and_user(endpoint, values):
client = Client.get(Client.subdomain == values.pop('client'))
The full source code can be found on Gitlab
__init__.py is the main app file. panel/__init__.py has the problematic code. This is the full traceback I receive:

cli = Client.select().where(Client.subdomain == client)

As you can see the database is actually connected, and the client table is available.
Edit 2:
Well, I just found that apparently just database.get_tables() will cause this error. However, that code does fetch all tables from the database...
Does url_value_preprocessor run before the database is initialized? That would be strange since I import the object calling this decorator after initializing the database.
I'm trying to enable "User-Restricted Resource Access" in my eve application with Basic Authentication. http://python-eve.org/authentication.html#user-restricted-resource-access
The Problem is since I enabled it I get for every http request on the API a "500 error"
If I fire up the API without basic authentication params I get a bad credentials error, so the Basic Authentication works fine.
This is the eve DEBUG Output:

I'm using eve 0.3 installed with easy_install
You are reading the documentation about the development version (as stated on all pages at python-eve.org.) One relevant change coming with v0.4 is the way auth tokens are set. So basically, you are applying 0.4-dev syntax to Eve v0.3. You should probably follow these instructions instead.
PS: 0.4 is due for release real soon so you might want to stick with that one, so you don't have to update your code again soon.
