tryapl down: the cause

i might have brought tryapl down for a moment just now. if that is the case, sorry about that.
here is what i was doing...

i wanted to see if i could evaluate expressions using cURL so i copied an `Exec` request from the browser and edited the final value in the array (the apl expression).

e.g.

i evaluated something like `⍳8` in the browser
then i changed `⍳8` to `9+⍳8` in the cURL request:

```bash
curl https://tryapl.org/Exec -H accept: */* -H accept-language: en-US,en;q=0.9 -H content-type: application/json; charset=UTF-8 -H origin: https://tryapl.org -H priority: u=1, i -H referer: https://tryapl.org/ -H sec-fetch-dest: empty -H sec-fetch-mode: cors -H sec-fetch-site: same-origin --data-raw ["SOME HUGE ENCODED VALUE HERE","9+⍳8"]
```
