Restfultable id's from objects

Hello, I’m trying to create a restfultable that displays the summaries of issues, as well as the issueKey of issues.

The reply from the rest API looks like this:


And then the correct ID for ‘issueKey’ is:

id: “issueKey”

But what is the correct ID for summary?
I have tried all the usual suspects:

fieldValues.summary, fieldValues[0] and so on.
