Before 6.6 I had an array with other arrays:

array(
    array( 'id' => 1, 'item' => 'item 1 name' ),
    array( 'id' => 1, 'item' => 'item 2 name' ),
    array( 'id' => 1, 'item' => 'item 3 name' ),
);

That create this JSON:

[
    {"id":1, "item":"item 1 name"},
    {"id":2, "item":"item 2 name"},
    {"id":3, "item":"item 3 name"},
]

The Interactive API created a context object that contains the array without problems.

Now, it just renders a string instead of an array object

To fix the error, I have to modify my array into this:

array(
    'data' => array(
        array( 'id' => 1, 'item' => 'item 1 name' ),
        array( 'id' => 1, 'item' => 'item 2 name' ),
        array( 'id' => 1, 'item' => 'item 3 name' ),
    )
);

Which created this JSON:

{
    "data": [
        {"id":1, "item":"item 1 name"},
        {"id":2, "item":"item 2 name"},
        {"id":3, "item":"item 3 name"},
    ]
}

This is indeed parsed as an object.
