Json array help

General

Hi, I am trying to use a function to access an outside defined ML model based on IBM. The requested format is specified as

-d '{"input_data": [{"fields": ["SENSOROUTPUTSTATUS", "TEMP", "HUMIDITY", "TIME"],"values": [$ARRAY_OF_VALUES_TO_BE_SCORED]}]}'

I am unsure how to define the "input_data" in the function. So far I've attempted the following:

msg.payload={};
msg.payload['fields']=["SENSOROUTPUTSTATUS", "TEMP", "HUMIDITY", "TIME"];
msg.payload['values']=[[US_SENSORSTATUS,TEMPERATURE,hum,READINGTIME]];
msg.payload['input_data']=[msg.payload['fields'],msg.payload['values']];

But I receive the following error "Scoring payload field 'input_data' is not in valid format. Excepted format is Json Array". How can I fix this? Thanks for any help

I think might be close to what you are after

var se = 1;
var te = 2;
var hu= 3;
var ti =4;
msg.payload = { "input_data" :[] };
var fields = ["SENSOROUTPUTSTATUS", "TEMP", "HUMIDITY", "TIME"];
var values = [se,te,hu,ti];
msg.payload['input_data'] = [{"fields": fields, "values":values}];
return msg;
