GalleryTV Error on I/O modifier:!empty

[moniarde]

I'm receiving an odd error message from the GalleryTV with the TV wrapped in an input output modifier. Here's my code:

[[*galleryCoverImage:!empty=`<div>
       [[*galleryCoverImage]]    
</div>`]]

This is the response I get:

<div>
      {"gal_src":false}    
</div>

The TV is empty, which is expected. But the error message shouldn't be showing. Can this error be turned off?
