Error: view_name.field_name no longer exists on explore_name and will be ignored

After you run an Explore or a Look, you might occasionally see the following warning:
⚠️ view_name.field_name no longer exists on explore_name and will be ignored.
This warning indicates that fields that you had previously selected or saved in an Explore or a Look are now no longer available. There are several potential causes for this occurrence:
The field or fields that are referenced in the warning exist only in Development Mode, and you're viewing the Explore or Look in Production Mode (or vice versa).
For example, if you see the warning users.name no longer exists on Companies, and will be ignored, this may indicate that the users view and its fields are no longer joined to the companies Explore and are therefore unavailable in the Look or Explore.
You can use the metadata panel in the IDE to see all explore definitions that reference a specific view.
A change was made to the view's name in its file, or the view reference in the explore LookML definition was changed with a parameter such as view_name.
For example, an underlying view for an Explore called users
was updated with a view_name parameter that references a view called customers:
explore: users {
view_name: customers
}
