3. Check whether the reflection expiration is set:
4. If it is a bucket remove issue, verify that the bucket is empty by running JCAS or another equivalent tool for running a Query:
CASScript>querySetExisting Query Expression Properties: Start Time: UNBOUNDED End Time : UNBOUNDED Type : EXISTING CASScript>query Performing clip query Query Expression Properties: Start Time: UNBOUNDED End Time : UNBOUNDED Type : EXISTING Number of clips returned: 0 All results returned: True
5. CAS objects have a 28-day quarantine period. Confirm that the time has lapsed. This means it can take up to 28 days for the associated blob to be removed when the clip is deleted.
If all previous steps are cleared and the bucket is still unable to be deleted, open a Service Request with Support.
