DataStore save function not updating array property correctly

Hi, I'm encountering an issue with the AWS Amplify DataStore save function when updating an object that includes an array property. When I use the DataStore save function to update an object with an array property, and the update input includes a new array value, the array property is not updated correctly and the new value is merged with any existing values.

Example: Suppose I have an object with an array property called "timeToArrive" that has the value [2, 4]. I use the DataStore save function to update the object, with an update input that includes the new value [1, 1] for the "timeToArrive" property:

const original = await DataStore.query(MyModel, id); await DataStore.save(MyModel.copyOf(original, updated => { updated.timeToArrive = [1, 1]; }));

Instead of setting the "timeToArrive" property to [1, 1], the DataStore save function merges the new value with the existing values, resulting in the value [2, 4, 1, 1] for the "timeToArrive" property.

Attempts to fix: I've tried using different approaches to update the array property, including copying the new values using a for loop or the spread operator, and using a custom resolver to update the object. However, none of these approaches have resolved the issue.

Expected behavior: I expect the DataStore save function to update the array property correctly, by setting the property to the new value without merging it with any existing values.

Current setup:

AWS Amplify version: 5.0.18 AWS services used: DataStore, DynamoDB Schema definition for model:

type MyModel @model { id: ID! timeToArrive: [Int] }

Any help or suggestions on how to resolve this issue would be greatly appreciated.
