Made few tweaks to your code. Try the below

a!forEach(
    items: local!constructData.lob,
    expression: if(
      count(
        index(
          local!constructData.advisorCode,
          wherecontains(
            fv!item,
            local!constructData.lob
          )
        )
      ) > 1,
      "Duplicate Line of business",
      ""
    )
  )

Few notes : tostring(local!constructData) will cast your entire data into a single text and wherecontains() won't work appropriately.
