Problem connecting data to table from API Connector

Hi,
]
I’m struggling with properly connecting data from external API to the data table.
I have created an API call like this


ans then set up a data source of a table like this:

It shows correct data if in the cell I set this
image
but not this
image

That’s a problem as later I want to pass current row entry to the popup and it doesn’t show any data.

What am I missing?

Thanks,
Maciej
