The workflow could not update the item, possibly because one or more columns for the item require a different type of information

Hi Purvish,

This issue may be due to the Approval workflow is corrupted.

I recommend to re-publish the OOB Approval workflow to SharePoint with the following steps:

1. Deactivate workflow feature from site collection.


2. Use SharePoint Designer and delete the OOB Approval workflow from the site collection.


3. Reactivate feature and verify Approval workflow is recreated.

Best regards,

Thanks
