Autonomous operator upgrade

Hi

We are using couchbase server 5.5 version with Operator 1.1.0.
I have upgraded to operator 1.2.0.
But after upgradation clusters are always stuck at provisioning state, if I see my couchbase pod logs I see :

slight_smile:
time=“2019-08-22T07:54:39Z” level=error msg=“failed to reconcile: unable to create bucketName named - cb-bucket-1jzm9kr75: [Server Error 400 (cb-1jzm9jg2u-0000.cb-1jzm9jg2u.cb-1jzm9jg2u.svc:8091/pools/default/buckets): [compressionMode - compressionMode can be set to ‘off’, ‘passive’ or ‘active’]], [Server Error 400 (cb-1jzm9jg2u-0001.cb-1jzm9jg2u.cb-1jzm9jg2u.svc:8091/pools/default/buckets): [compressionMode - compressionMode can be set to ‘off’, ‘passive’ or ‘active’]], [Server Error 400 (cb-1jzm9jg2u-0002.cb-1jzm9jg2u.cb-1jzm9jg2u.svc:8091/pools/default/buckets): [compressionMode - compressionMode can be set to ‘off’, ‘passive’ or ‘active’]]” cluster-name=cb-1jzm9jg2u module=cluster

Do I need to pass in additional configurations or is there any official guide for up gradation guide ?
