ajax response returns undefined

[pidgypost]

I have the latest CMB2 beta build installed through wordpress plugin directory.
I uploaded your plugin through SFTP and network activated.
I added your input type to my test file.
The input shows up fine.
I get an error when trying to search.
Line 143 throws console error saying response.data is undefined. response var outputs -1

I am getting the exact same error and my steps are just like pidgypost's.

My code is like this:

$custom_page->add_field( array( 'name' => __( 'Find an article', 'cmb2' ), 'id' => $prefix . '_articles', 'type' => 'post_search_text', 'show_option_none' => false ) );

I am thinking there should be some options passed, but I am not sure in what format.
