Getting Invalid JSON error in Dev console-CodePudding

I'm making a react app and want to connect it to my Back4App database. I have a Person class in the Back4App dashboard with data that should be returned, it seems like the call is being made but I am getting an error in the dev console. I am initializing Parse correctly so I don't think it's an issue with that. Any help very much appreciated!

Error that I'm getting: Dev console error

Code for call:

export async function fetchUser() {
    // create your Parse Query using the Person Class you've created
    const query = new Parse.Query('Person');
    // use the equalTo filter to look for user which the name is John
    query.equalTo('name', 'Jakob');
    // run the query
    const user = await query.first();

    return user;
}

the error says that

http://localhost:3000/classes/Person

is not found, are you sure this is the correct route? because it can't be found
