Issue with reusing dashboard on another index

Hello Joe,

Im trying to use saved objects api via the dashboard file i got it from export saved object, however, it is throwing me 400 bad request

xyz@x:~/6may$ curl -v POST "localhost:5601/api/saved_objects/_bulk_create" -H 'kbn-xsrf: true' -d @dashboard.json

{"statusCode":400,"error":"Bad Request","message":"\"value\" must be an array","validation":{"source":"payload","keys":["value"]}}

Here is my dashboard file which is in json format.

Kibana Dashboard - github

Is the format in which im sending data needs change?
