[icrxy3dtufi2]

File "/app/account/views.py", line 283, in before_request
and request.endpoint[:8] != 'account.'
TypeError: 'NoneType' object is not subscriptable

Facing error with some urls due to error above

Please help and suggest

Something may help:

    if current_user.is_authenticated \
            and not current_user.confirmed \
            and request.endpoint != 'static':
        try:
            if request.endpoint[:8] != 'account.' :
                return redirect(url_for('account.unconfirmed'))
        except:
            pass

Thanks
