How to create Primary Index for password protected buckets in Couchbase

Question

I have a bucket name user-account with password 'user' and I am trying to create Primary Index on this bucket

 CREATE PRIMARY INDEX ON `user-account`

but its giving

{
"requestID": "83e90d2d-18dc-4eb7-af34-7d689d962c8a",
"signature": null,
"results": [
],
"errors": [
    {
        "code": 13000,
        "msg": "Failed to create view #primary - cause: error installing view: 401 Unauthorized / {\"error\":\"unauthorized\",\"reason\":\"password required\"}\n"
    }
],
"status": "errors",
"metrics": {
    "elapsedTime": "15.466089ms",
    "executionTime": "15.260122ms",
    "resultCount": 0,
    "resultSize": 0,
    "errorCount": 1
}
}

If I remove the password then that same code is working.

Can anyone suggest me any solution for this.. Any help will be appreciated..!!!
