Googletrans API AttributeError

I keep getting "AttributeError: 'NoneType' object has no attribute 'group' " error even after changing gtoken on googletrans stopped working with error 'NoneType' object has no attribute 'group' but I got __init__() got an unexpected keyword argument 'client' error instead

here my main.py

from fastapi import FastAPI, Request
from fastapi.templating import Jinja2Templates
import uvicorn
from googletrans import Translator
#init
app = FastAPI(debug=True)

templates = Jinja2Templates(directory="template")


#route
@app.get('/')
def home(request: Request):
    text = request.get('text')
    lang = request.get('lang')
    #print('text:',text,'lang:',lang)

    #connect the translator
    translator=Translator()

    #detect langguage
    dt = translator.detect(text)
    dt2 =dt.lang

    #translate the text
    translated = translator.translate(text, lang)
    tr =translated.text

    return templates.TemplateResponse({"request": request},"translates.html",{'translated':tr,'u_lang':dt2,'t_lang':lang})

#def translator(request):


if __name__=="__main__":
    uvicorn.run(app,host="127.0.0.1",port=8000)

and here where my translate.html execute the translate within site

<form action="" method="get">
    <br>

<div class="form-input">
    <center><label for="TextareaInput">Enter Text </label></center>
    <center><textarea class="form-control" value="text" id="TextareaInput" rows="3"></textarea></center>

        <h1>Text succes translated {{u_lang}} to {{t_lang}}</h1>
        <center>
            <h1>{{translated}}</h1>
        </center>
    </div>
</div>
</form>

I already hit wall because this error keep popping

Solution

A new alpha version with a fix was released a few minutes ago.

Install the alpha version like this:

pip install googletrans==3.1.0a0

Important thing to note: You have to specify a service url, otherwise the same error still occurs. So this should work:

from googletrans import Translator
translator = Translator(service_urls=['translate.googleapis.com'])
translator.translate("Der Himmel ist blau und ich mag Bananen", dest='en')

But his still returns the error (at least for me):

translator = Translator()
translator.translate("Der Himmel ist blau und ich mag Bananen", dest='en')
