Data Pusher not run when creating uploding a resource via File Store API

I'm struggling to get the data pusher to run against a resource that was uploaded via the File Store Api.

Created a package using package_create in postman, then added a resource to that using resource_create.

When I submit a resource via the web app the datapusher runs and successfully adds all 999 rows to the datastore.

Is there something I'm missing?

Running version 2.8 of CKAN and the latest version of the data pusher.
