Dimension in object "Viz: xxx" references non-existent Master Dimension "yyy"

The chart object references a Master Dimension that is not present in the Master Library.

This condition can when a developer removes a Master Dimension from the library without realizing the Dimension is in use.

Because Master items are referenced by id only, the field or label of the missing Dimension is unknown.

The chart must be edited to remove or replace the Dimension reference.
