Failed: Add Items to deletion group, from Excel VB add-in using ItemsV2 Rest api.

Summary:

We are working on deleting on some old absolute items, where we build a Excel VB add-in using ItemsV2 Rest API to mass upload items to a deletion group.

We are receiving a failure message as "Failed: Add Items to deletion group", This row has been modified by another user. Please download before editing.

Couldn't find any relevant sources to understand the error, tried all possible check and retries but couldn't succeed. If anybody has any inputs or ideas to resolve this error will be highly appreciated.
