I noticed that when I am developing a Django App in debug mode, I sometimes see this output on my server stdout:
Traceback (most recent call last):

Can someone tell me why this is happening?
The browser closed the socket connection before the server could finish sending the response (e.g. you closed the tab before it loaded all the way). Don't worry about it.

Any idea, where I should look into it. Let me know if you need any specific file.
This simply means that self.status is somehow returning a None value. So insert a check and try like this:
if self.status != None:
self.status.split(' ',1)[0]
There are some exceptions from my running GCF (--runtime python37 --trigger-topic <pubsub_topic> --retry).
They are all from this IP 169.254.8.129 which should be GCP internal IP and maybe the supervisor of GCF. I google this IP and grab the deploy output (via Node)
{
“SUPERVISOR_HOSTNAME”: “169.254.8.129”,
...
“X_GOOGLE_SUPERVISOR_HOSTNAME”: “169.254.8.129”,
}
(https://rominirani.com/google-cloud-functions-tutorial-using-environment-variables-20b4f0f82aa0)
From Stackdriver Logs, the GCF will have ConnectionResetError after this exception, and then this GCF will exit with failure errors.

Is it one bug of GCF? How to prevent this exception from developer's perspective?
I'm currently trying to use my school's LDAP with a website built with Django. But i'm encountering an error that I'm not able to tackle.
When I am using my school's network the LDAP log in works perfectly on localhost. But when i am using an off-campus network the log-in doesn't work, even the admin login created when i've run manage.py for the first time doesn't work.
The terminal display's the following error each time i try to login :

Thank you very much for your help !
This is an issue with the Django devserver (you are running your website using it, which is not recommended at all for production websites).
Please see this ticket for more details:
According to many sources the 'Broken Pipe' is a normal browser quirk. For example, the browser reads from the socket and then decides that the image it's been reading apparently didn't change. The browser now this (forcefully) closes the connection because it does not need more data. The other end of this socket (the python runserver) now raises a socket exception telling the program that the client 'Broke the socket pipe'.
Short answer is: ignore this error since it's a known error and won't be fixed.
There is also this SO thread talking about this issue.
I have a setup containing varnish nginx and 2 pyramid backends one of them running socket.io app. All the stack works correctly on my local development computer, but i can't get to work the websocket part on the production computer. The traceback of the error that trows the socketio app when a client socket.io tries to connect:

I've checked all python packages versions and there are identical in both computers. Also upgraded production computer to libevent 1.4.14b to match local computer.
I don't know which way to go to debug this. Help appreciated!
Hi I am doing papal integration with my django app.
i am using latest version of django from svn and python 2.6.
However, i found every time when paypal's sandbox accessing my notify url i got 500 [Errno 32] Broken pipe my django stack.
Does anyone have similar experience with this ?
Cheers,

error: [Errno 32] Broken pipe
----------------------------------------
The first error Connection reset by peer show you that the connection have been closed by peer (in your case Pypal) and for the Error Broken pipe this error is raised when a connection is closed suddenly without informing the other peer (in your case your machine).
There are two problems. First, some of the paypal APIs (particularly MassPay) are terribly poor.
The second, and more likely, problem, is that your server is single-threaded and is having trouble properly raising an exception to paypal. I was able to resolve a similar problem by creating an html file with a form (via POST) that mocked a paypal IPN and then looking at the debug result (or better, using a debugger like the one in PyDev). You could do the same thing with curl of course.
