Please note that the error message will continue for already affected Opportunities because the added product has missing data. if you must reuse existing opportunities, those can be fixed by below steps:
1. Perform the scoping change, which is a pre-requisite for any solution.
2. Delete existing products from the existing opportunities.
3. Re-add the products to the opportunities.
this you could do in mass fashion using Data Workbench with the Opportunity Product object. we would suggest just go with the easier route of using new opportunities.
