What it means

The page tried to display a whole bundle of data (an object) as if it were plain text. It needs to be told which specific field to show, like the name instead of the whole customer record.

I'm getting "Objects are not valid as a React child". Using the keys listed in the error, find where an object (or a Date, or a Promise) is rendered directly in JSX. Change it to render the specific field (e.g. item.name), format dates with toLocaleDateString(), or map over arrays. If an API now returns a different shape, adapt only the rendering code. Do not modify unrelated components.

If the AI can't fix it: manual steps

  1. Search your code for the field names shown in the error message (found: object with keys {...}) to locate the spot.
