Apache NiFi JoltTransformJSON processor attribute as jolt spec

I have a JoltTransformJSON processor. I want to use the FlowFile attribute (containing the Jolt spec) as the specification.

When I attempt to do it, there is a validation error "JSON Spec provided is not valid JSON format".

I use NiFi 1.6

Is it possible to specify jolt spec as an attribute? attribute as jolt spec validation error

Jolt Specification supports NiFi Expression Language but only for substituting the values inside the spec. That is:

Say you have a NiFi attribute : jolt.operation: shift you can refer that inside your spec as:

[
    {
        "operation" : ${jolt.operation},
        ...
        ...
    }
]

The entire spec cannot be sent as a flowfile attribute, at least as of now.
