When I type a message and click on send, it gives an error saying Method Not Allowed.

You need to be logged in

[AyushSehrawat]

It's after logged in only

[Ziyaulmustafa]

I faced same issue, after I logged in

[justin-mathews]

Same, I logged in and tried to post a message. Received 405 (Method not allowed). Also noticed the socket.io polling update returns a 400 (Bad Request)

[samarmohan]

Do you guys have the sockets properly configured?

[justin-mathews]

Do you guys have the sockets properly configured?

All I've done is git clone the repo, create virtualenv, run pip install -r requirements.txt and python main.py

From there the site loaded with login page, I logged in and got the Home page then tried posting a message and received 405.

Also when the server launches I get this message The client is using an unsupported version of the Socket.IO or Engine.IO protocols (further occurrences of this error will be logged with level INFO) Tried changing in base.html to but I get the same message.

For reference running this on Pop!_OS 20.10

Yes, this patch fixed the issue with the "unsupported version of the Socket.IO or Engine.IO Protocols". Thanks. Are you planning to submit this patch?

[AyushSehrawat]

@justin-mathews It worked for me :), thanks.

[AyushSehrawat]

This issue was probably due to version of socket-io

[TechStudent10]

I know I am late to the party but #3 should work 😁

Yeah , the pr was made after this issue only. Still Tim didn't approve till now

@AyushSehrawat maybe it's because @techwithtim is a bit busy and can't check some of his old repos.

Hi, that's due to the bad practice of not specifying the dependencies versions on the requirements.txt:

Thanks a million! I got that issue too, and now it's gone! Thanks!

Someone should close this issue now.

I think this issue should not be closed until specifying dependencies versions in requirements.txt.

[elpython3]

I believe flask should be at least version 1.1.1 and up, looking at the livestream.

[hadialqattan]

I believe flask should be at least version 1.1.1 and up, looking at the livestream.

I believe that the dependency which causes the issue is flask-socketio (not flask).

[hadialqattan]

The issue is that flask-socketio version is not compatible with the socket.io version in the index.html.

Hi, I am also facing this issue now, it worked really well yesterday but the issue appears today and I am unable to solve it (already replaced with this line in my base.html () but still doesn't work all. Anyone knows how to solve this issue?

[elpython3]

@ApacheT101 Did you modify anything other than that line? Assuming you didn't, try restarting the server, computer, etc. It generally works for me when stuff like that happens. @hadialqattan I tested out if dependencies versions worked (by manually installing flask-socketio versions), and I discovered flask-socketio versions 5 and up works (at least, on my ubuntu 20.04). Anything else either doesn't send or has the Method Not Allowed error.

I tried to restart the computer and server before and even reinstall every imports in another laptop to test the script (no modification except change ip address in env file) but the error codes still comes up. Could you try to execute script on your laptop?

[elpython3]

@ApacheT101 I just executed the code on my end. It works for me.
