Migrating IAP according to documentation gives console error.

Background I am trying to upgrade an old project to use the new IAM, moving from Addon to using the Package manager version 3.x. I am using Unity 2019.4.19f1 and on a MacBook Pro. Following these instructions (https://docs.unity3d.com/2019.4/Documentation/Manual/com.unity.purchasing.html)

Problem I got to step 3 but after deleting the whole folder with the subfolders, Assets/Plugins/UnityPurchasing/*

I had to go back and restore a specific file since the editor was complaining about it:

It feels like there is some reset that needs to be done, or some refresh / regeneration of folders?

I did also use the Windows -> Unity IAP -> Delete for/Prepare for upgrade to 3 option.

The Error from Console is pasted below for reference
