Issue with a repeat with a repeat

I have an api which returns the records I require to insert into my database, however I am not sure if the company has set it up wrong (not that I can change it)
On the images the api returns an object then inside it an array (see below)

When I add the repeat within the repeat it does not give me options to add the output fields (see below)

on the insert for this I have add {{url}} which is the item in the repeat, however I am getting the error:

core.repeater: repeat is required.

(/opt/node_app/lib/core/app.js:524:23)\n at App.repeat (/opt/node_app/lib/modules/core.js:18:29)\n at App._exec (/opt/node_app/lib/core/app.js:491:57)\n at App._exec (/opt/node_app/lib/core/app.js:458:28)\n at processTicksAndRejections (internal/process/task_queues.js:97:5)\n at async App.exec (/opt/node_app/lib/core/app.js:427:9)\n at async App.repeat (/opt/node_app/lib/modules/core.js:80:17)\n at async App._exec (/opt/node_app/lib/core/app.js:491:30)\n at async App._exec (/opt/node_app/lib/core/app.js:458:17)\n at async App.exec (/opt/node_app/lib/core/app.js:427:9)"

Does anyone have any ideas about this as it is driving me crazy.
