`Hi everyone,`

`I'm building my first AI Agent workflow and I'm facing a very strange issue on the final step. I'm really close, but completely stuck!`

`My goal is simple: An AI Agent talks to a user and outputs a JSON string with the collected lead data. The next node, ClickUp, should create a new task with this data.`

`The Problem:` `The workflow runs successfully (all green nodes!), and a task IS created in ClickUp. However, the task is created with empty fields. The static text from my expression (like " **Empresa:**") is written correctly, but the dynamic part`{{ … }}`seems to evaluate to an empty string.`

`I'm using this expression to get the lead's name:` `{{ JSON.parse($json.output).json.dados.nome_lead }}`

`This seems to be a silent failure in the expression engine. I've already tried:` `- Using an Edit Fields node to parse the JSON first (it returned null).` `- Double-checking the data path, which seems correct based on the AI Agent's output.`

`I'm attaching a few screenshots showing the AI Agent's successful JSON output, and the final empty task created in ClickUp.`

`Is this a known bug, or is there a better way to reliably parse a JSON string from a previous node for the ClickUp fields?`

`Thank you so much for any help!`

hello @Relitore

That’s because the `JSON.parse` function fails as you have improper JSON.

You should enable the option “Require specific output format” and specify the JSON schema to output

Another option is to clean and parse the output after defining the agent’s output. You can use a Set or Code node to convert the output into a real JSON object. For example, in a Code node:

```auto
const raw = $json.output;
// Extract only the valid portion of the JSON
const match = raw.match(/\{[\s\S]*\}/);
if (!match) {
throw new Error("Could not extract valid JSON");
}
const parsed = JSON.parse(match[0]);
return [{ json: parsed }];

```

Then, in ClickUp, access the data directly.  
After that, you can use simple expressions like:

```auto
{{ $json.dados.name_lead }}
{{ $json.dados.name_company }}

```

And they’ll work correctly because you’re no longer trying to JSON.parse(…) a string with double quotes and escaped newlines.
