Errors Related to Client.__del__

[0xRar]

Hey there, my functions are working fine but when i run my script without my arguments i get errors, any idea how to fix it?

Exception ignored in: <function Client.__del__ at 0x0000000003DB9160>

I updated & Im still getting errors, i tried with 2 machines now 😥, can you guys test if the problem is fixed for you?

Hello @0xRar,

127 should fix the problem. Can you test it again?

Thanks!

Hey @mgmacias95,

No, its still there, the errors im getting are kind of different than other people.

Hello @0xRar,

Can you post a traceback of the exact error you're getting?

Thanks!

@mgmacias95,

Its the same traceback as the one up top but it changed a little because i upgraded to python 3.11,

just a declaimer everything works when using a specific function that interacts with vt-py, so its just a visual error that happens when running the script without using a function that uses vt-py.

Example1: python script.py (will run and show the error) Example2: python script.py -h (will run and show the error) Example3: python script.py --analyze_url https://virustotal.com/ (will run as expected and not show any error at all)

[mgmacias95]

Testing the following script:

import vt
import asyncio

async def main():
  c = vt.Client('xxx')
  result = await c.scan_url_async('https://google.com/', wait_for_completion=True)
  print(result)
  await c.close_async()

asyncio.run(main())

With a python 3.11 docker image, I was unable to reproduce the error. Can you share some details about the script you're running?

Thanks!

I have similar issues. I tried examples/upload_files.py and try to upload two files. and here is a traceback.

I did little tweak like you suggested, like,

async def upload_hashes(queue, apikey):
  """Uploads selected files to VirusTotal."""
  return_values = []

  async with vt.Client(apikey) as client:
    while not queue.empty():
      file_path = await queue.get()
      with open(file_path, encoding='utf-8') as f:
        analysis = await client.scan_file_async(file=f, wait_for_completion=True)
        print(f'File {file_path} uploaded.')
        queue.task_done()
        return_values.append((analysis, file_path))
        await client.close_async()

  return return_values

Hello @NaSangWon,

Please, open a new issue next time. Otherwise it's quite tricky for us to manage (this issue is already closed).

Looking at your code, you're closing the client twice: one by doing await client.close_async() and other when exiting the async with vt.Client block (the context manager closes the client for you).

This is how the code should look:

async def upload_hashes(queue, apikey):
  """Uploads selected files to VirusTotal."""
  return_values = []

  async with vt.Client(apikey) as client:
    while not queue.empty():
      file_path = await queue.get()
      with open(file_path, encoding='utf-8') as f:
        analysis = await client.scan_file_async(file=f, wait_for_completion=True)
        print(f'File {file_path} uploaded.')
        queue.task_done()
        return_values.append((analysis, file_path))

  return return_values
