manage-bulk-documents action fails with incorrect Cloudant request body

[brunogirin]

When I use the manage-bulk-documents action, it fails because the query sent to Cloudant is not a JSON object. The action expects a JSON object with a docs key that contains an array of documents and so does Cloudant. However, the action only sends the array without the container object and the docs key. So what Cloudant receives is:

[{"_id":"0399a368b906664af2d0e39de79a8ccf","_rev":"1-d55be7137d8447de7062c9ffed88341c","_deleted":true}]

while it expects:

{"docs":[{"_id":"0399a368b906664af2d0e39de79a8ccf","_rev":"1-d55be7137d8447de7062c9ffed88341c","_deleted":true}]}

The action should retain the container object with the docs key to ensure that what is passed to Cloudant is correct.

Steps to reproduce

Send the manage-bulk-documents action a query like:

{
  "docs": [ actual docs go here ],
  "dbname": "mydb"
}

It will fail with the error indicated below.

Workaround

A workaround is to send the action an object like this:

{
  "docs": {
    "docs": [ actual docs go here ]
  },
  "dbname": "mydb"
}
