Nice use of dependencies array, empty means the logic inside the useEffect will be executed once.

Just a minor suggestion here, if the variable is a boolean, naming it as isLoading, setIsLoading, isError ... is more intuitive.
This reference is of Java but I think this convention is widely adapted

Instead of deciding the rendering within return, do you thiink moving the condition out and returning accordlingly is more readable?
if(loading) {
retrun (
<div>Loading...</div>
)
}
if(error) {
return (
<div>Error</div>
)
}
return (
<>
...

FYI there is another way to update the state setOrders( (order) => order + 1). in this case the result is the same.

if the variable is a number type rather than an array, it is better to name it order, orders implies it is an array.

Nice use of Spread ... to update the state
