When updating the Team Board, creating new project or a variety of other screens and actions, the user is presented with a similar error. The field name and values listed can vary depending on your environment. Here are two error messages for different fields as examples:
Error with the State field on Defects:
Validation error: The allowed values must be unique. RatingScheme{name='null', ratings={[Duplicated, Closed, Verified, New, Cannot reproduce, Open, Discarded, Reopen, In progress, Not defined, Resolved, Working as designed, Won't Fix]}}.configuration.defectStateRatingScheme.ratings(ordinals)[7] is already an allowed value.
Error with the Environment field on Defects:
Validation error: The allowed values must be unique. RatingScheme{name='null', ratings={[Prep, Disaster Recovery, Test, Prod]}}.configuration.defectEnvironmentRatingScheme.ratings(ordinals)[3] is already an allowed value.
Take a moment and identify which field and which work item type is affected by looking at the error message that you received.
There is an internal "ordinal" number that keeps track of the order of the values for a field and two of them have the same ordinal number. The error indicates that there is a duplicate ordinal number.
This fix should take a few seconds, so there is minimal impact to users.
To correct the issue as a Workspace or Subscription Admin;
The error should no longer appear as you resume your previous activity.
