Datastore.query returns undefined when user logs out and logs in again.React JS Amplify about amplify-js HOT 4 CLOSED

Hi @MeryAmun 👋 thanks for raising this issue.

When the user logs in or out, we typically recommend clearing the local store in case other users login to the same device.

If in your case you can and/or want to leave the data in the local store, please disregard.

In any case, I'm curious how you might be doing things in your app. Can you share some code snippets such as your graphql schema, how you are configuring Amplify and/or DataStore, calling DataStore.query, as well as any error logs?

Another option would be if you could provide specific reproduction steps for us to follow to reproduce the issue internally, or even a small sample app that reproduces the issue.

hello @chrisbonifacio thank you for your prompt response. Here is the code snippet for datastore query

useEffect(() => {

const removeListener = Hub.listen("datastore", async (capsule) => {
const {
payload: { event, data },
} = capsule;

console.log("DataStore event", event, data);

if (event === "ready") {
  const shops = await DataStore.query(Shop, Predicates.ALL);

  setShop(shops[0]);
  setLoading(false)
}

});
DataStore.start()
return () => {
removeListener();
};
}, []);

Also I wish to mention that I am using the withAuthenticator HOC

@MeryAmun, can you clarify if you're running DataStore.stop() or DataStore.clear() on/before a user logs out? If they are not being called when a user logs out then I don't think a new ready event is going to be emitted from Hub after calling DataStore.start() because it has already started, which might cause the issue you're experiencing.
