FastAPI AttributeError: 'Depends' object has no attribute 'query'

I’m trying to access my database with fast API. I’m having some problems getting access to it if done it outside of an endpoint.

I’m trying to access the DB and retrieve the allowed emails. I can do that in the get/post (/refresh) endpoints, but not in the route (/token), it throws the error: ”Depends’ object has no attribute ‘query”

From what I understand the depends can only be solved in an API route, so I tried to create a new post endpoint and call it from the route. The result is that the request gets stuck…

@router.route('/login')
async def login(request: Request):
    #REQUEST GET STUCK IN PENDING
    await requests.post(url="http://localhost:8000/auth" + '/set-users')
    
    redirect_uri = FRONTEND_URL  # This creates the url for our /auth endpoint
    return await oauth.google.authorize_redirect(request, redirect_uri)

@router.post('/set-users')
def set_useres(database: Session = Depends(db_handler.get_db)):
    emails = brand_operation_handler.get_all_users(db=database)
    print(emails)
    allowed_email_in_user_table_setter(emails)
    return ''

@router.route('/token')
async def auth(request: Request, database: Session = Depends(db_handler.get_db)): #,  database: Session = Depends(db_handler.get_db)
    try:
        access_token = await oauth.google.authorize_access_token(request)
    except OAuthError:
        raise CREDENTIALS_EXCEPTION
    user_data = await oauth.google.parse_id_token(request, access_token)

    
    #emails = brand_operation_handler.get_all_users(db=database)
    # allowed_email_in_user_table_setter(emails)



    if (valid_email_from_db(user_data['email'])): #or valid_email_from_user_table(user_data['email'])
        return JSONResponse({
            'result': True,
            'access_token': create_token(user_data['email']),
            'refresh_token': create_refresh_token(user_data['email']),
            'user_data': user_data
        })
    raise CREDENTIALS_EXCEPTION


@router.post('/refresh')
async def refresh(request: Request, database: Session = Depends(db_handler.get_db)):
    
    #THIS WORKS
    emails = brand_operation_handler.get_all_users(db=database)
    print(emails)
    allowed_email_in_user_table_setter(emails)

    try:
        # Only accept post requests
        if request.method == 'POST':
            form = await request.json()
            if form.get('grant_type') == 'refresh_token':
                token = form.get('refresh_token')
                payload = decode_token(token)
                # Check if token is not expired
                if datetime.utcfromtimestamp(payload.get('exp')) > datetime.utcnow():
                    email = payload.get('sub')
                    # Validate email
                    # database: Session = Depends(db_handler.get_db)
                    # get_user_table(database)
                    if valid_email_from_db(email): #or valid_email_from_user_table(email)
                        # Create and return token
                        return JSONResponse({'result': True, 'access_token': create_token(email)})
