Trello Custom Field Value Not Showing in Make

What are you trying to achieve?

Hi,

I’m trying to extract an email address stored in a custom field on a Trello card and use it as the recipient in an email automation.

The custom field is a text field containing an email address.
I use “Get a Card”, which retrieves customFieldItems, but I don’t see the email value in the email module.
I know the correct idCustomField, but I can’t extract the value properly.
The email address doesn’t appear as an available option when setting up the email module.
However, when I click on the “Get a Card” module in Make, I can see the custom field values and the email address in the output.
How can I correctly retrieve and use the email value from the custom field in my scenario?

Thanks!
