Question: Should I be concerned with this? Our feedback is Yes!
How do I solve this?
Don’t fear! There are a set of recommendations or workarounds that will help resolve these warnings. Remember to identify what the buttons and links do and refer to the following guidelines from Salesforce:
If the button opens a list view using custom URL parameters, replace them with a Visualforce custom button. Else, create a Lightning component.
Create a Lightning component and give users access by:
Invoking access from a Lightning component action or
Use Lightning App Builder to add the Lightning component to a Lightning page.
Create a Lightning component. Add “force:hasRecordId” interface and <aura:attribute name=”recordId” type=”Id”/> attribute to obtain ID from the current object. Then set up a Lightning component action so users can access it.
