Lua data not being rendered on pongo2 template

I'm using algernon to try to output data from a lua script into a pongo2 template.

In the code below number_list outputs exactly as I'd expect but nothing renders for object_list.

What am I doing wrong?

title = "This is the title"

number_list = {}

table.insert(number_list, 1)
table.insert(number_list, 2)
table.insert(number_list, 3)

object_list = {}

o1 = {1}
table.insert(object_list, o1)
o2 = {2}
table.insert(object_list, o2)
o3 = {3}
table.insert(object_list, o3)

<html>
  <head>
    <title>{{title}}</title>
  </head>
  <body>
    {{ title }}
    <div>

        {% for item in number_list %}
        test 1: {{item}} 
        {% endfor %}

        {% for item in object_list %}
        test 2: {{item}}
        {% endfor %}
    </div>
  </body>
</html>

edit: Turns out it's a bug. Check out @IdeaToCode answer or the bug report for a different way to do it.

I don't know lua but in most languages objects need to have keys. I ran this using algernon and it appears to work as you intended.

example.lua:

title = "This is the title"

number_list = {}

table.insert(number_list, 1)
table.insert(number_list, 2)
table.insert(number_list, 3)

object_list = {}

o1 = {id = 1}
table.insert(object_list, o1)
o2 = {id = 2}
table.insert(object_list, o2)
o3 = {id = 3}
table.insert(object_list, o3)


serve2("example.html", { object_list = object_list, number_list = number_list})

example.html:

<html>

<head>
    <title>{{title}}</title>
</head>

<body>
    {{ title }}
    <div>

        {% for item in number_list %}
        test 1: {{item}}<br>
        {% endfor %}

        {% for item in object_list %}
        test 2: {{item.id}}<br>
        {% endfor %}
    </div>
</body>
