Describe the bug

I have a table for which for couple of fields, I changed the type from String to array of String from the Data under Setup from Admin UI. After updating and deploying the latest changes, in the admin UI, when I go to the Content from the Manage and select the table which I recently updated, is showing an error with type mismatch.

Expected behavior

The table in Data Manager from Manage should be updated with the updated field types.

Reproduction steps

1. Create Data Model using the Amplify UI with some fields of type String
2. Deploy changes and pull latest changes in your environment
3. Update one of the field from String to String Array
4. Deploy latest changes in your environment and generate the model files
5. Go to the Content Under Manage in Amplify UI and select the updated table

Hey @SUK109, thank you for reaching out. This is currently expected behaviour on DataStore when modifying an existing field on a Data model to a different type. If the associated DynamoDB table has records in them, you will need to manually backfill and update the records.

@ykethan , thanks for your response. Can we have it mentioned anywhere in the documentation?
