PyDrive 2.0 – AuthenticationError: No code found in redirect

Set-up

I'm using PyDrive 2.0 to connect to the Google Drive API.

def connect_google_drive_api():
    
    import os   
        
    # use Gdrive API to access Google Drive
    os.chdir('/Users/my/fol/ders/access_google_drive')
    from pydrive.auth import GoogleAuth
    from pydrive.drive import GoogleDrive
    
    gauth = GoogleAuth()
    gauth.LocalWebserverAuth() # client_secrets.json need to be in the same directory as the script
    drive = GoogleDrive(gauth)
    
    return drive

The working directory /Users/mypath/access_google_drive contains the client_secrets.json, which looks like,

{"web":{"client_id":"xxx","project_id":"invoice-creation-290413","auth_uri":"https://accounts.google.com/o/oauth2/auth","token_uri":"https://oauth2.googleapis.com/token","auth_provider_x509_cert_url":"https://www.googleapis.com/oauth2/v1/certs","client_secret":"xxx","redirect_uris":["http://localhost:8080/"],"javascript_origins":["http://localhost:8080"]}}

where I replaced the real client_id and client_secret with xxx.

Issue

When the browser (Safari 14.0) shows Gdrive api link wants to access your Google Account and I click Allow, the process seems to be stuck.

After 20 seconds or so, the following error is shown,

Failed to find "code" in the query parameters of the redirect.
Try command-line authentication
Traceback (most recent call last):

  File "<ipython-input-36-792f41ab7318>", line 1, in <module>

    raise AuthenticationError("No code found in redirect")

AuthenticationError: No code found in redirect

How do I solve this?

I was importing connect_google_drive_api() into another script, say script x.py.

Both the connect_google_drive_api() function and x.py had the line os.chdir('/Users/my/fol/ders/access_google_drive') to set the working directory to where the client_secrets.json was.

With the following code, I actually make a connection without any issue,

def connect_google_drive_api():
        
    # use Gdrive API to access Google Drive
    from pydrive2.auth import GoogleAuth
    from pydrive2.drive import GoogleDrive
    
    gauth = GoogleAuth()
    gauth.LocalWebserverAuth() # client_secrets.json need to be in the same directory as the script    
    
    drive = GoogleDrive(gauth)
    
    return drive

Was trying to run this code from a Jupiter notebook. I was able to successfully authenticate when I switched browsers from Safari(14.0.1) to Chrome(87.0.4280.88)
