unable to run , unknown encoding: base64

[changchichung]

when I try to run the playbook , there is an error message

fatal: [jm-router.abc.com]: UNREACHABLE! => {"changed": false, "msg": "EOF on stream; last 300 bytes received: u'Traceback (most recent call last):\\n  File \"<string>\", line 1, in <module>\\nLookupError: unknown encoding: base64\\n'", "unreachable": true}
	to retry, use: --limit @/home/mini/ansible/playbook.test.retry

do you have any ideas ?

coreutils-base64 should be installed
