I am looking at reading information from firestore. So I followed the examples from here. Here is my code. It's a Flask application which calls the firestore client.
#menuapi_routes.route("/api/menu")
def get_menus():
menu_items = get_menu_items()
retval = []
for item in menu_items.stream():
retval.append(u' {} => {}'.format(item.id, item.to_dict()))
return json.dumps(retval)
The code which is getting called is.
def get_menu_items():
db = firestore.Client()
doc_ref = db.collection(u'menus')
return doc_ref
The error I get is
127.0.0.1 - - [16/May/2020 22:09:24] "GET / HTTP/1.1" 404 -

That repo contains the error. As the traceback informs you, values is not allowed there, but you can use value. Change it locally and it should resolve the error. Additionally, you could make a pull request to that repo and help the original author(s) by fixing a bug in their code.
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:

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:

This code here

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 attempting to use sendmail within flask to send some emails - but the error message coming back are a bit cryptic.
from flask.ext.sendmail import Message
from flask.ext.sendmail import Mail
mail = Mail()
mail.init_app(app)
msg = Message("Hello".encode('utf-8'), sender="xxx#xxx.com".encode('utf-8'), recipients="xxx#xxx.com".encode('utf-8'))
msg.body = "testing"
msg.html = "testing"
mail.send(msg)
The problem appears at mail.send(msg). Here is the full trace:

TypeError: 'str' does not support the buffer interface
Where is the likely culprit?
Have a look at this example

File "<stdin>", line 1, in <module>
TypeError: 'str' does not support the buffer interface
It's the same error you've got, so don't encode the str values you're using.
