(redis-om & fastify) this.writeEntity is not a function - redis

Question

I'm learning to use the Redis for my backend database and I would like to try using redis-om for fastify not sure whether they are compatible or not, but I got error.
I use service of app.redislabs.com
I don't know what I just messed up? And how can I fix the problem?
server.js
const { createCar, createIndex } = require("./redis");
app.post("/add", async (req, res) => {
await createIndex();
const { make, model, image, description } = req.body;
const data = { make, model, image, description };
await createCar(data);
res.code(200).send('ok');
});
const PORT = 5000;
app.listen(PORT, function (err) {
if (err) {
app.log.error(err);
process.exit(1);
}
});
redis.js
const { Client, Entity, Schema, Repository } = require("redis-om");
const client = new Client();
const connect = async () => {
if (!client.isOpen()) {
await client.open("redis://default:password#localhost:6379");
} else {
console.log("CONNECTED");
}
};
class Car extends Entity {}
let schema = new Schema(
Car,
{
make: { type: "string" },
model: { type: "string" },
image: { type: "string" },
description: { type: "string" },
},
{ dataStructure: "JSON" }
);
const createCar = async (data) => {
await connect();
const repository = new Repository(schema, client);
const car = repository.createEntity(data);
const id = await repository.save(car);
return id;
};
const createIndex = async () => {
await connect();
const repository = new Repository(schema, client);
await repository.createIndex();
};
module.exports = {
createCar,
createIndex,
};

You cannot call new on Repository. This is a breaking change I introduced in version 0.2.0 of Redis OM. There are a couple of others that are documented in the CHANGELOG.
Call const repository = client.fetchRepository(schema) instead, as shown here. Unfortunately, there are some videos and blogs that have the older syntax and so this crops up from time to time.
Thanks for using my library!
