@FozzieN , You can do exactly what you're trying to achieve using standard NiFi processors and a schema to describe your data structure. Please see attached a flow example that replicates what you are doing without the need for scripting. This flow uses the following schema, set as a parameter: {
"type": "record",
"name": "MyData",
"fields": [
{ "name": "source_timestamp", "type": "string" },
{ "name": "signal", "type": "string" },
{ "name": "value", "type": "string" },
{ "name": "fecha_envio", "type": ["null", "string"], "default": null }
]
} Cheers, André
