What happened

detail.render was given a string or a class, not the documented function. Neither form ever drew anything, so the detail region is left empty and this one warning is logged rather than failing silently.

The fix

Pass detail.render a function (container, row, ctx) that mounts into container and returns an object with a destroy() method, or nothing.

The smallest fix

detail: { render(container, row) { container.textContent = row.key; return { destroy() {} }; } }
