Query throws NullPointerException on empty Datastore with limit #1532

Closed Rayv1 closed 2 years ago

Rayv1 commented 2 years ago

Description

Hi, when querying empty datastore with limit, it throws:

DataStoreException (DataStoreException(message: An unknown exception has happened. Please take a look at
https://github.com/aws-amplify/amplify-flutter/issues to see if there are any existing issues that
match your scenario, and file an issue with the details of the bug if there isn't., recoverySuggestion: We currently don't have a recovery suggestion for this exception., underlyingException: java.lang.NullPointerException: null cannot be cast to non-null type kotlin.Int))

Code:

final res = await Amplify.DataStore.query(
  FoodTransaction.classType,
  pagination: new QueryPagination( limit:10),
);

Its working fine without the QueryPagination and empty datastore.

Thanks @Rayv1 for reporting this issue.

Can you run the App in Android Studio and paste the logs around executing your code example here?

cshfang commented 2 years ago

Hi @Rayv1. I was able to reproduce this issue and I believe it to be a duplicate of #842.

As a workaround, you can provide the page parameter with a 0 value when constructing your QueryPagination. In the meantime, I will close this issue in favor of the original issue and try to provide some additional info to the original issue to see if we can get the appropriate people looking into it.

If you feel that this is a different issue and that it has been closed in error, please feel free to reopen. Thank you!
