Seems like there is an invalid username in your list.

for read-only display, richTextDisplayField is the better practice.

a!richTextDisplayField(
  label: "Requested On Behalf:",
  labelPosition: "ADJACENT",
  value: joinarray(
    a!forEach(
      items: a!defaultValue(ri!MDSRequest.requestedonBehalf, {}),
      expression: if(
        a!isNullOrEmpty(fv!item),
        {},
        user(fv!item, "firstName") & " " & user(fv!item, "lastName")
      )
    ),
    ", "
  ),
  showWhen: a!isNotNullOrEmpty(ri!MDSRequest.requestedonBehalf)
)
