CHW-4604 PolicyConflict
policy conflicts with an existing one (duplicate name or precedence); pick a unique identifier or precedence
Default message: policy conflicts with an existing one (duplicate name or precedence); pick a unique identifier or precedence
HTTP status:409(client)
Problem. The submitted policy collides with an existing one.
Cause. Either the policy name (ErrDuplicatePolicy) or its
precedence value (ErrDuplicatePrecedence) is already claimed by
another policy in this org. Fix. Pick a unique name or shift the
precedence to an unused integer; precedence values do not need to be
contiguous. HTTP 409.
