Set Content Approval status using workflow

Hi All,

 I am new to SharePoint .I am using SharePoint Online List 2019. I Created Approval Workflow using SharePoint Designer.It was working fine.I need to Set the Content Approval Status of that item to 'Approved'.When I tried to do that after my task complete action I get the following error in Work Flow History

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

Please help me! I am searching for a fix for this problem.

Thanks
