Flask flask_uploads.UploadNotAllowed error - python

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")

Flask doesn't see the static file

Regards, It's been seeing my static files by now. I am using VS Code as an editor. I clicked accidentally debug mode and then it stopped seeing my static files. I started VS Code again but the result hasn't changed. How can I solve this problem? When I open localhost, it shows 127.0.0.1:5000/static/css/main.css but it gives an error when I display the page source and open the css file on the new page.
The error I get in the browser is: TypeError: make_conditional() got an unexpected keyword argument 'accept_ranges'
The error I received in VS Code is as follows:
127.0.0.1 - - [12/Dec/2018 23:17:50] "GET /static/css/main.css HTTP/1.1" 500 -

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".

Peewee 'Connection already open' in url_value_preprocessor with Flask

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:

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.

Its Dangerous creating a token: cannot concatenate 'str' and 'NoneType' objects

I have an email confirmation feature on my Flask application. For this to work, I must create a token which will go in a confirmation link. To create the token I'm using Its Dangerous like so:
from itsdangerous import URLSafeTimedSerializer
ts = URLSafeTimedSerializer(app.config["SECRET_KEY"])
token = ts.dumps(email, salt='email-confirm-key')
confirm = url_for('confirm', token=token, _external=True)
After running this, I receive an error stating cannot concatenate 'str' and 'NoneType' objects from the following traceback:

I'm unsure what the issue is, as email is a string and the salt is one too. What could be the problem? Thanks.
The issue is this line:
ts = URLSafeTimedSerializer(app.config["SECRET_KEY"])
It looks like your app.config["SECRET_KEY"] is not being set correctly. If you replace that line with this
ts = URLSafeTimedSerializer('test')
You should find that it works. So you need to find out why app.config["SECRET_KEY"] is not being set correctly.

"TypeError: hashpw() argument 1 must be str, not bytes" when trying to register a user with flask-security

I'm trying to create a small flask application using the Enferno framework, but when I try to register a user I get an error that seems to be generated by the passlib library. I can't understand if it's something I did or if it is an error in the library itself.

I just ran into this. Turns out, I had installed both bcrypt and python-bcrypt in my virtualenv. passlib.hash.bcrypt has a check to see which version on bcrypt is present. By removing the python-bcrypt, I was able to cease this error from being thrown.
