Describe the bug:
Attu fails to load data after using the Milvus Backup & Restore tool. When a collection is created, then modified using Alter Field to add a new field, and data is inserted into that field, the backup and restore process completes but loading the data in Attu results in an error. This suggests the backup tool may not correctly handle schema changes (added fields) or Attu cannot read restored data with altered schema.

Steps to reproduce:
Create a collection in Milvus.

Use Alter Field to add a new field to the collection schema.

Insert data into the collection including the newly added field.

Run Milvus Backup Tool to create a backup.

Restore the backup to Milvus.

Open Attu and try to load/view the restored collection data.

An error occurs while loading the data.
