issue in deleting container

[marswhc]

HI, I'm trying to perform the command below and it's failing. Do you know how to fix it?

[root@gpfs1 /]# swift delete swift-ui An unexpected error occurred whilst deleting: Expecting value: line 1 column 1 (char 0)

[root@gpfs1 /]# swift list swift-ui Traceback (most recent call last): File "/usr/bin/swift", line 10, in <module> sys.exit(main()) File "/usr/lib/python2.7/site-packages/swiftclient/shell.py", line 1287, in main globals()['st_%s' % args[0]](parser, argv[1:], output) File "/usr/lib/python2.7/site-packages/swiftclient/shell.py", line 458, in st_list raise stats["error"] simplejson.scanner.JSONDecodeError: Expecting value: line 1 column 1 (char 0)
