I got the following error in a live site where a utf character (test string 'Îñţérñâţîöñåļîžæ†îøñ') was submitted:

I can fix this using <form type="POST" accept-charset="utf-16">.
Normally, I catch errors in application code and log them or email them to myself, but this error never reached my application code which runs on TurboGears 1.5.
Any idea on how I can hook in to catch and log errors generated by CherryPy, and secondarily, give the user a better 404 page?
The method of error handling listed at _cperror.html#unanticipated-errors
doesn't work for this sort of error (but kicks in on e.g. static file missing)

I am trying to run a music bot on a vps running ubuntu. Everything works fine when I run the bot on windows, but when I move it over to my linux vps and use my skip command, it gives me an error: ValueError: I/O operation on closed file. I am not sure how to fix this as it seems to be entirely to do with discord.py's inner workings, as you can see the code simply calls the ctx.voice_client.stop() method.
I have tried looking online and cannot find anyone who mentions this issue, so I believe it to be a problem specific to me, but I cannot figure out why it works on windows and not linux. Here is the command:
#commands.command(name='skip', description="skips to the next song in queue")
async def skip_(self, ctx):
"""Skip the song."""
vc = ctx.voice_client
if not vc or not vc.is_connected():
embed = discord.Embed(title="", description="Not connected to a voice channel")
return await ctx.send(embed=embed)
if not vc.is_playing() and not vc.is_paused():
return await ctx.send("**Nothing is playing**")
vc.stop()
Here is the full error:

Please help on this its a been a blocker for me.
This is because I was hitting http://localhost:4569 which isn't a user interface. So its throwing error.But if I create tables using aws cli and do some operations it just works fine without any issue.
I am making a program using tkinter that executes some code from different files.
This is the part of my code causing problems:
text=textbox.get('1.0','end-1c')
FYI: textbox is a tkinter.Text object defined by a different file that my code executed
when ever I execute my code, I get the error:
Exception in Tkinter callback
Traceback (most recent call last):
File "/anaconda3/lib/python3.7/tkinter/__init__.py", line 1705, in __call__

return self.tk.call(self._w, 'get', index1, index2)

what is going wrong?
That error means that you're trying to access a widget that has been destroyed.
I am trying to follow a post over creating and running a Rasa bot
Steps already did:
- I could get all working folders
- Got the basic data files
- Trained Nlu and Core
- launched action server and command line
- So here the expectation is User enters Input like 'Hi or hello' and then bot responds and continues the chat
Actual results: Seeing below error.
make cmdline
python -m rasa_core.run -d models/current/dialogue -u models/current/nlu --endpoints endpoints.yml

On preliminary search over forums, seems it is a Python code issue, as I understand it try to get bot responses using 'WITH' keyword ?
Any pointers on how can I get it sorted please ?

I've just installed python 3.2.1 (32-bit) and cherrypy 3.2.1 (CherryPy-3.2.1.win32-py3.exe) on my Windows 7 box and have tried the hello world example (executed via PyScripter) but it hangs after the Engine bus STARTED message.
If I try to start it via the python.exe, I get the following log:

What am I missing?
Code:
import cherrypy
class HelloWorld:
def index(self):
return "Hello world"
index.exposed = True
cherrypy.quickstart(HelloWorld())
EDIT: Bonus-info: I've tried various things to remedy the situation with no result. Installing the 64-bit version of python didn't help as cherrypy doesn't support 64-bit (unless, I'm mistaken). I've tried re-installing both python and the cherrypy packages, and I've tried deactivating all other things that might block it (IIS). All to no avail :-(
EDIT2: Second bonus - everything works if I install it with python 2.7.2, so seems it is only a problem with 3.x (I've tried 3.0.1 as well - same problem)
I have encountered two errors:
1 - open your browser before starting the script, so you'll not have any problem.
2 - if you use a personal firewall or an antivirus that handles HTTP protection, be sure he is not protecting the 8080 port, for example ESET Antivirus will not let you use the 8080 and CherryPy will say that the port is not free.
