AttributeError: 'NoneType' object has no attribute 'group' in googletrans

Question

I want to convert unknown language strings to English. For which I’m using googletrans python package that works along with an API to perform the desired task

So, I did following

from googletrans import Translator
translator = Translator()
translator.translate('안녕하세요.', dest='ja')

This gave

---------------------------------------------------------------------------

      2 translator = Translator()

     64         code = code.encode().decode('unicode-escape')

AttributeError: 'NoneType' object has no attribute 'group'

What is causing the error? Is there any other way around to achieve the task.

As I have tested your scenario using your code, I also encountered the same error as seen in this screenshot.
Testing using googletrans 3.0.0

This is likely due to the old library version that you’re using which is googletrans 3.0.0

To resolve the issue you are encountering, you must upgrade your googletrans from 3.0.0 to 4.0.0rc1. You may use below script to upgrade your googletrans version.

pip install googletrans==4.0.0rc1

Please see below successful testing using googletrans 4.0.0rc1 for your reference:
