Describe the bug

I found a bug in your codebase in initializeModel function - the reduce there returns property value instead of accumulator reference which causes an error in the second iteration.

1. First iteration

2. Second Iteration

Expected behavior

sortKeyValues reduce should return acc instead of one of its field value

if (record[curVal]) {
   acc[curVal] = record[curVal];
}
return acc;

Reproduction steps

Call initializeModel function

Hi @WojciechKasprzyk,

Thank you for bringing up this issue! A new version of the package (@aws-amplify/data-schema version 1.16.0) was released and the accumulator return type has been fixed.

Thanks,
Jack
