This is transient. Sending such requests, either on a local instance or the live instance, does not automatically trigger the exception. However, the exception occurs after a request on some package.json. Can this be related to size? All are in the 300KiB range or over.

The actual code at this position is

raise Not_found

The code that calls this is here:

  let find : type a. a def -> set -> a option =
  fun k s ->
    try match M.find (Key.V k) s with
    | V (k', v) -> k.of_univ (k'.to_univ v)
    with Not_found -> None

AFAICT. This makes me wonder if this is a strange runtime or linking bug. I don't see how this exception could be generated, if the backtrace is correct, and the exception printer is correct. But if the runtime is indeed constructing a Failure exception when the caller expects to catch Not_found, this would seem like a runtime problem. I don't see an issue about count_while1 in the OCaml repo, maybe this has been reported in different form.

Could you cc someone from the compiler team?

I would probably do a pin of Logs with an additional | Failure _ -> assert false case or similar, that might help to confirm that there really is a Failure exception being raised, and it is here (and so the printer and backtrace are actually correct).

The actual string count_while1 does not seem to appear in the repos of Dream, Logs, or OCaml, at least I haven't found it with grep.

According to sherlocode, count_while1 seems to come from angstrom, which is an ocaml.org dependency through uri.

Ah. It's also a dependency through Dream (through http/af), among, probably, other paths.
