I have create a user with the user license as "SalesforcePlatform", here i create some custom permission sets to assign for that user. The Permission set having the System permission access as "Insert System Field Values for Chatter Feeds". If i assign the permission set to the new user it throws the error like as "Can't save permission set ChatterPermissions, which is assigned to a user with user license Salesforce Platform. The user license doesn't allow the permission: Insert System Field Values for Chatter Feeds ". Is there any other possibilities to add the Permission sets to the user with same access?
