When I attempt to run the extension I receive the following error.

2020-06-06 10:01:28.924513-0400 Extension[1256:43618] Failed to inherit CoreMedia permissions from 1246: (null) { }

At first I thought that I was missing a permission something like NSCareMediaUsageDescription, but that does not exist. Has anyone see this problem?

Thanks, Tom

It's happening the same to me. Anyone?

App extensions need to be in the same app group as the app they extend.

@deirdresm can you elaborate please?

Realized the project wasn't working because i was a missing an opening curly bracket in Action.js run: function(parameters) {

Failed to inherit CoreMedia permissions from ... will still appear but it also appears on paul's video if you pause the video at 4:26 on "Establishing communication – JavaScript Injection, part 5"
