Next.js mongoose returns only 20 records although no filter is set

I have the problem that when I work with Next.js and the revalidate method /getServerSideProps, my result only ever contains 20 data although there are 112. If I change the whole thing to 'no-store', all 112 data are returned. I use the App Router method.

The strange thing is that in the GET method where the call to mongoose takes place, I can see all the records. However, only 20 in the action.js

app/Products/route.js:

export async function GET(request) {
try {
 await mongoConection();
} catch (error) {
 console.log(error);
}

const products = await Product.find({}).sort({
 createdAt: -1,
});

//Products length = 112
console.log("Products length" + products.length);

return NextResponse.json({ products });

}

app/FetchProducts/action.js:

"use server";

export async function FetchProducts() {
const result = await fetch(`${process.env.NEXT_PUBLIC_URL}/Products`, {
 next: { revalidate: 3 },
});

const expected = await result.json();

//expectedlength = 20
console.log("expected length: " + expected.products.length);

return expected;

}

app/FetchProducts/page.js:

 const fetchProducts = async () => {
 setLoadMore(true);

 const fetching = await FetchProducts();

 //ONLY 20 Result
 setResult(fetching.products);

 setLoadMore(false);
};

from here

in GET route you are not using fetch. that is why you are getting all the results. but in actions you use fetch and probably your first fetch request returned only 20 and those were cached.
