**My app code is here that i implement as a whole wrapper i provide everything but still getting the error **

I have created a simple react app to fetch data from an api. Basically it should only display the name of a material given from the api. When I call the api in the browser, it shows the JSON data correctly.
Now when I reload my frontend page the following error message is displayed:
Error: Only plain objects, and a few built-ins, can be passed to Client Components from Server Components. Classes or null prototypes are not supported.
