The attached alternative code sample (which i've actually tested this time) will demonstrate how you can manually sort your text array (using officially supported functionality), and using a the specified pagingInfo value, select just the first result automatically (which should be the highest). Let me know if you have any questions.

with(
  local!array: {
    "2018-12-04T19:24:44",
    "2017-09-26T20:41:35"
  },
  
  todatasubset(
    a!forEach(
      local!array,
      {
        text: fv!item
      }
    ),
    a!pagingInfo(
      startIndex: 1,
      batchSize: 1,
      sort: a!sortInfo(
        field: "text",
        ascending: false()
      )
    )
  ).data.text
)

My mistake, max() does expect a numeric value. The place I've used it for finding the max date from a list is being called on an array of dateTime value.

Thanks for the suggestion Mike. I tried to use the max function and for ( List of Text String: 2 items "2018-12-04T19:24:44" "2017-09-26T20:41:35") and this is what I got -2.017093e+13

I believe dates in that format will sort lexically consistently (i.e. a standard "alphabetical" sorting will sort the dates correctly, assuming they're TEXT and with no other conversion necessary), in which case I'd expect the "max()" function might work for you.
