Custom code block output not working

[BVowles]

Hi there HubSpot community. I'm new to Data Hub and hoping someone can help with an issue we're having.

We have a custom code block that when it runs it should:

• take the deal ID of the enrolled deal
• look to see what deals are associated with the enrolled deal (they'll only be one)
• return the deal ID of the associated deal as a data output; parentDealId

However, when ever the code block runs the out put always returns this error message:

'Not defined in code'.

Below is the code we're using and a screenshot of the setup and the results output. Thank you for your help!

exports.main = async (event, callback) => {
const dealId = String(event.inputFields.hs_object_id || '');
const TOKEN = process.env.Account_API_Key;

if (!dealId || !TOKEN) return callback({ parentDealId: '' });

try {
const url = `https://api.hubapi.com/crm/v4/objects/deals/${dealId}/associations/deal`;
const res = await fetch(url, {
method: 'GET',
headers: { Authorization: `Bearer ${TOKEN}`, Accept: 'application/json' }
});

if (!res.ok) return callback({ parentDealId: '' });

const data = await res.json();
const parentDealId = data?.results?.[0]?.toObjectId
? String(data.results[0].toObjectId)
: '';

return callback({ parentDealId });
} catch (e) {
return callback({ parentDealId: '' });
}
};

I have managed to sort this. The code needed an output field wrapper:

return callback({ outputFields: { parentDealId } });
