I am using flask-dance to authenticate to Google's servers.
Config for flask-dance:
from flask.ext.dance.contrib.google import make_google_blueprint
google_blueprint = make_google_blueprint (
client_id=app.config['GOOGLE']['client_id'],
client_secret=app.config['GOOGLE']['client_secret'],
scope=["profile", "email"],
redirect_to="main.index",
login_url="/",
authorized_url="/authorized",
)
app.register_blueprint(google_blueprint,url_prefix="/login")
However, I am getting Warning: Scope has changed from "profile email" to "". after you go through Google's credential dialog box.
Here's the full trace:

If I do os.environ['OAUTHLIB_RELAX_TOKEN_SCOPE'] = '1' it works, but I don't think this is a solution but more of a workaround for now. :(
I opened a ticket on the issue Google OAuth2 returns no scope on authentication breaks scope test #306 on the issue.
From what I can tell from https://www.rfc-editor.org/rfc/rfc6749#section-3.3, Google isn't required to return the scope (unless the scope was changed), am I reading this correctly?
Nearest thing I can figure is there is a bug in the oauthlib plugin which I opened a bug report with already.
From the bug report, you can fix the issue by changing the file /oauth2/rfc6749/tokens.py in the plugin on Line 30 from self._new_scope = set(utils.scope_to_list(params.get('scope', ''))) to self._new_scope = set(utils.scope_to_list(params.get('scope', old_scope)))
Fix was merged: https://github.com/idan/oauthlib/pull/323

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.
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:

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.
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.

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.
