Invalid argument supplied for foreach()

I have set up a custom field with the following:

Field type: Photo Gallery
AE Post Template Layout: Global
Rule: post type equal product profile (where I’m storing related images to be displayed)

AE Templates:
Post template
Using ACF Gallery widget
Set field with photo gallery field api

Throws the following error:

Warning
