React-query is returning data as undefined and isLoading is always true

Question

on react native in a random scenario react-query get stuck in loading state where isLoading is always true and the data is undefined.

I checked the cache using the flipper-react-query-native plugin, I found that the data is saved in the cache but it's not returned.

can anyone help me?

I scratched my head for a long time on this one. This may be the solution for you! This resolved things on my end. I realized after testing out any promise, they'd never resolve. That's when I found this github issue.

Actually, I fixed the issue by fixing the implementation of my code, I was passing the mutate function as route params which caused this problem. I found out that passing non-serializable variables in route params will create some problems in react native app.

Ah, yep. That'll do it. Glad you were able to solve the problem!

You can use this approch in your code:

  const { isLoading, data, isFetching } = useQuery(...)
  const loading = isLoading && isFetching;

Now you can obtain the current loading state by performing this action.
