Hi, guys i'm uploading file using this code

const entrypoint = process.env.REACT_APP_API_ENTRYPOINT;
const fetchHeaders = {Authorization: `Bearer ${window.localStorage.getItem("admin_token")}`};

    ...options,
    headers: new Headers(fetchHeaders),
});

    </ListGuesser>
)
const GameImageList = props => (
    <ListGuesser {...props}>
        <FieldGuesser source="filePath"/>

const dataProvider = baseHydraDataProvider(entrypoint, fetchHydra, apiDocumentationParser);


export default () => (
    <HydraAdmin
        dataProvider={dataProvider}
        authProvider={authProvider}
        entrypoint={entrypoint}
    >
        <ResourceGuesser name="users" list={UserList}/>
        <ResourceGuesser name="games" edit={GameEdit} create={GameCreate}/>
        <ResourceGuesser name="game_images" show={GameShow} list={GameImageList} create={GameImageCreate}
                         edit={GameImageUpdate}/>
    </HydraAdmin>
);

I'dont know if it's an issue or not but, i've got a first request which upload my file with respond code 201 so all is fine, but after a second request is making with the response of the upload request, i don't know why
