numbers.already_claimed
The inventory row is already assigned to a workspace and cannot be claimed again.
numbers.already_claimed is returned when a number claim request targets an inventory row that has already been assigned to a workspace. This is a conflict that indicates the number was taken between the inventory browse and the claim attempt.
Another workspace or a concurrent request claimed the number before this request completed. This is a time-of-check/time-of-use race on inventory rows.
Choose a different number from inventory and retry the claim. The number list should be refreshed to reflect current availability.
