[robertSt7]

Actual behavior

Steps to reproduce

  updateAsset
  (
    id : 320,
    input :
    {
      metadata : 
      [
        {
          name:"title",type:"input",data:"title_test_edited_by_n8n"
        }
      ] 
    }
  )
    {
      success
    }
}

This is how core API works as it refreshes the records in db. If the requirement is to update or append only the metadata then we should add new property as an improvement.
