Syntax error on `not same as`

[aszenz]

Syntax error is thrown, twiggy doesn't seem to understand not same, if i remove not it doesn't show any error.

{% if env() is not same as 'some_value' %}
    {# Add your logic here for when the environment is 'some_value' #}
{% else %}
    {# Add your logic here for other cases #}
{% endif %}
