“Undefined index: path” on wp_insert_post

I’m trying to create a WordPress post using PHP, and something’s going wrong and I can’t figure it out. My background is not PHP, and no traceback is being delivered to me–just this error by itself:

Error: Undefined index: path

Here is my post creation code:

function generate_query_args($campaign_id, $user_id) {
    $query_args = array(
        'post_parent' => $campaign_id,
        'post_author' => $user_id,
        'posts_per_page' => -1,
        'post_status' => 'publish', /*array('publish'),*/
        'paged' => '',
        'log_type' => 'sale',
        'post_title' => 'Autogenerated by Heroku setup',
        'post_content' => '',
        'post_excerpt' => '',
        'tax_query' => array(
            array(
                'taxonomy' => 'edd_log_type',
                'field' => 'slug',
                'terms' => 'sale'
            )
        )
    );
    return $query_args;
}

$post_id = wp_insert_post(generate_query_args($campaign_id, $user_id));

As far as I can tell from the docs, I’m doing everything I’m supposed to be.

Update:

This is the entirety of what I run and see in return:

>> $post_id = wp_insert_post($query_args, true);
Error: Undefined index: path

I’m using WordPress console.

WordPress 3.9.1 running Fundify Child Theme theme.

Post-mortem:
Ultimately, this may have been an error with the Console plugin, since when I simply ran the code as part of WordPress, it ended up working.
