Uncaught Twig_Error_Syntax: Unknown "json_encode" function

Hello Forum members.

in my opencart 3.0.2.0 i have a module now this module gives me an error see the code below

Uncaught Twig_Error_Syntax: Unknown "json_encode" function in "default/template/extension/module/notification.twig" at line 22. in /home/mk4design/public_html/system/library/template/Twig/ExpressionParser.php:574 Stack trace: #0 /home/public_html/system/library/template/Twig/ExpressionParser.php(351): Twig_ExpressionParser->getFunctionNodeClass('json_encode', 22)

if i check the file i see 3 lines that are not correct and they are

Cities : {{ json_encode(city) }},
Names : {{ json_encode(cname) }},
Products : {{ json_encode(products) }},

Below the complete notification twig file, could any one help me with this error.
Thanks in advance.

<div id="fnotification-{{ module }}" class="f-notification animated">
<div class="notification-block">
{% if (notification['close_status']) %}<button class="fclose-notification">×</button>{% endif %}
<div class="notification-image">
{% if (custom_icons) %}
{% if (thumb) %}
<img src="{{ thumb }}" title="{{ title }}" alt="{{ title }}">
{% endif %}
{% else %}
<i class="fas fa {{ font_icon }}"></i>
{% endif %}
</div>
<div class="notification-text-block">
<div class="notification-title">{{ title }}</div>
<div class="notification-text"></div>
</div>
</div>

That module is free?
You can try to contact developer.

It's a paid extension and the developer doesn't reply on my mails to help me. There was another php file that wasn't correct i repaired it self but de json encode error in twigfile, i don't no much about the json encode functions.

Attach .tpl file here. (or entire module on PM)

I will try to convert

LE. You can't download 3.x version? I see is a 3.x version
