How to get AI Agent to output raw data

Describe the problem/error/question

Is there a way to get the AI Agent node to output the raw result? Currently, it outputs the result as a string inside a JSON object, like so:

[
   {
      "output": 
      "As of the most recent data, the top 5 most populated countries in the world are:\n\n1. **China** - Approximately 1.41 billion people\n2. **India** - Approximately 1.39 billion people\n3. **United States** - Approximately 332 million people\n4. **Indonesia** - Approximately 276 million people\n5. **Pakistan** - Approximately 225 million people\n\nKeep in mind these numbers are continually changing due to births, deaths, and other factors."
   }
]

The issue with this is that connecting a structured output parser that structures the response (if the response is JSON) fails because it’s a string.

Here’s an example of the response with a JSON answer:

[
{
"output": 
"{\n "countries": [\n {\n "name": "China",\n "population": 1411778724\n },\n {\n "name": "India",\n "population": 1387297452\n },\n {\n "name": "United States",\n "population": 331893745\n },\n {\n "name": "Indonesia",\n "population": 276362965\n },\n {\n "name": "Pakistan",\n "population": 225199937\n }\n ]\n}"
}
]

Given this, is there a way to get the AI Agent node to only output the raw result, so that it can work with the Structured Output Parser?

Hello @Praxder

The JSON.parse($json.output) method should be able to parse it

Is there a way to do that between the AI Agent and Structured Output Parser?

Well, as I get it, the Output parser is how the model should return data. But I’m not an AI expert

I figured it out. For anyone in the future with the same issue: the problem was that the JSON Schema I was passing to the Structured Output Parser was pretty complex and it had trouble parsing it. Simplify your schema until you find the property that won’t map.
