Echosign is setting a password to a document when I have set it not to.

Hi I have an app and want to send some document to sign to the users. I am using rest api V3.

I am able to send and sign the documents by the POST method on /agreements with following JSON

       `"options": {

            "noChrome": false,

            "authoringRequested": false,

            "autoLoginUser": false

        }

        documentCreationInfo:

          name: 'freeName'

          message: 'hello'

          recipients: [

            {

              securityOptions:[

                {

                  authenticationMethod: "NONE"

                }

              ]

              email: 'email@email.com'

              role: 'SIGNER'

            }

          ]

          fileInfos: [ {

            'documentURL':

              'name': 'fileName'

              'url': 'myUrl'

              'mimeType': 'application/pdf'

          } ]

          signatureType: 'ESIGN'

          signatureFlow: 'SENDER_SIGNATURE_NOT_REQUIRED'

          postSignOptions:

            "redirectDelay": 0

            "redirectUrl": "myCallbackUrl"

          "securityOptions": {

            "passwordProtection": "NONE",

            "kbaProtection": "NONE",

            "webIdentityProtection": "NONE",

            "protectOpen": false, (notice no password set)

            "internalPassword": "",

            "externalPassword": "",

            "openPassword": ""

          }`

Even though I have set not to include password, while viewing the document with /{agreementId}/combinedDocument,

it is asking me the passport while viewing the document from the app. What am I doing wrong?
