JoltTransformJSON EL when using file

[Matthew Hawkins]

Hi devs,

Using 1.23.0 I have a simple transform adding some flowfile attributes into
the content.
When putting the spec directly to the processor it works fine. If I have
the spec in an external file however it seems to put in the literal string
${attrname} - ie the EL didn't process.

Have I done something incorrectly or should I be now asking for an account
to log a bug?

Sample spec run using Chain DSL:

[{
  "operation": "shift",
  "spec": {
    "@": "values"
  },
  {
    "operation": "default",
    "spec": {
      "firstname": "${firstname}"
    }
  }
]

Kind regards,
Matthew
