Data Mapper: "Copy" doesn't work for JSON's array of strings

[niphlod]

Describe the Bug

Suppose I have this source

{
   "field1" : "example",
   "field2" : [
       "x1",
       "x2",
       "x3"
    ]
}

and the destination

{
   "fielddest1" : "example",
   "fielddest2" : [
       "x1",
       "x2",
       "x3"
    ]
}

It seems that the "Copy" function of the data mapper doesn't work with a "simple" array of strings (mapping "field2" to "fielddest2")....

Plan Type

Standard

Steps to Reproduce the Bug or Issue

1. create a source and a destination schema that entails an array of strings e.g.

"fielddest2": {
                    "type": "array",
                    "items": {
                        "type": "string"
                    }
                },

2. try to map the source array to the destination array

No response

Additional context

This doesn't seem to be supported in the "legacy" data mapper nor the "modern" one.
