Entity Storage: "Entity not found"

[dasldaksjlksadasj]

I’ve downloaded the entity-storages-sample, and am trying to use

const entity = client.db.entity({ version: "v1" });
entity.get("todos");

but the error I get is

{
    "message": "entity not found",
    "status": 404,
    "errorSource": "APP"
}

This happens both when using it on the client and serverless.

The only thing I have changed from the repository is support_ticket to service_ticket.

Am I the only one having trouble?
