Description

In a scenario where the AM API V3 aggregate is queried for a slice which has no resources local to the aggregate, the incorrect error is returned.

Here is the sequence that show the error:

  1. Create a slice: ($omni.py createslice lnv3)
  2. Describe the slice, which has no resources at the V3 aggregate:
    $ omni.py describe lnv3  -a ig-gpo

The error is for slice credential, which is not the proper reason for this failure. Error needs to reflect that the aggregate has no resources for the requested slice.

No change in this AM API V3 issue. When the slice has no resources, the error reports that bad credentials are used rather than no resources exist.
