Error after installing the module on opencart. What to fix?

Question

opencart

After installing the news module on the site on the opencart in the admin panel, the following message appears:
Notice: Undefined index: token in /home/c/cq24052/opencart_1/storage/modification/admin/controller/common/column_left.php on line 117
The specified line looks like this:

'href'     => $this->url->link('catalog/news', 'token=' . $this->session->data['token'], true),

What is wrong there and how to fix it?
Thank you.

In version 3, token was replaced with user_token
