loop contexts(loop.last, loop.index ...) are happening issue Inside for loops on volt,

[kelvinengineer]

Recently, I upgrade phalcon 3.x to 5.x and php version 7.x to 8.x.
I'm facing issue in for loops.

Here is error message:
count(): Argument #1 ($value) must be of type Countable|array, null given

Here is the code.

{% for policy in policies %}
      <option>{{ policy['title'] }}</option>
      {{ loop.last ? '' : '<option data-divider="true"></option>' }}
{% endfor %}

It works fine if I remove {{ loop.last ? '' : '<option data-divider="true"></option>' }}
