failed execute of enpty function

I get this error, when I try to execute function:
Traceback (most recent call last):
File "/usr/local/server/src/server.py", line 165, in handler
output = await asyncio.wait_for(execute(context), timeout=safeTimeout)
File "/usr/local/lib/python3.9/asyncio/tasks.py", line 479, in wait_for
return fut.result()
File "/usr/local/server/src/server.py", line 158, in execute
output = userModule.main(context)
TypeError: main() missing 1 required positional argument: 'res

that function is a pre-1.4.0..is this a new function created in 1.4?

yes, i created it by "init function" in 1.4

perhaps you're using an old SDK. what's the output of appwrite -v?

1.1.1

Ya that's really old. You should be using version 4.0.0

How I can update CLI?

How did you install it previously?

curl -sL https://appwrite.io/cli/install.sh

You can try running that again

actually don't install it that way...

Can you uninstall it by deleting the binary?
