When I run pytest

pytest

There are three test failed:

=================================================== short test summary info =================================================== 
FAILED test_fg.py::test_translate_multi_new_mod - AttributeError: 'NoneType' object has no attribute 'group'
FAILED test_fg.py::test_translator_false_input - FileNotFoundError: [WinError 2] The system cannot find the file specified: '...
FAILED test_fg.py::test_translate_failsafe - AssertionError: assert 'falsely modified' == 'something to say'

I am wondering what caused this. I am currently trying to see if there is any flaky tests in test design so I need to get all tests pass at first.

First, I use pip install Flask-Googletrans and successfully installed the extension.
My app.py is as bellow:

`from flask import Flask, render_template
from flask_googletrans import translator

app = Flask(name)
ts = translator(app)

@app.route('/')
def hello_world():
title = "hello"
title = ts.translate(text=title, src='en', dest=['ja'])
return render_template("index.html", title=title)

if name == 'main':
app.run()
the jinja template file is as bellow:

{{ title }}

When running on http://127.0.0.1:5000, I got errors as bellow:

What should I do to deal with the error? Thank you for your time.
