What does the error message "Error: Objects are not valid as a React child (found: Error: Request failed with status code 404)" mean?

edit

This error message typically indicates that there was an error when attempting to fetch data from an API endpoint (HTTP status code 404 indicates that the requested resource was not found). The error message is indicating that the response from the API request included an Error object, and that this type of object cannot be directly rendered in a React component. To resolve the problem, you may need to revise your code to handle different types of API response objects correctly, and to display relevant error messages to the user when necessary.
