Add more details to fromJson error

[Chriscbr]

I tried this:

bring http;
bring cloud;

struct Pokemon {
  id: str;
  name: str;
  order: num;
  weight: num;
}

new cloud.Function(inflight () => {
  let x = http.get("https://pokeapi.co/api/v2/pokemon/ditto");

  // response status
  log(x.status);

  let data = Json.parse(x.body);

  // Cast response back into struct
  let ditto = Pokemon.fromJson(data);
  log(ditto.name);

});

This happened:

I got an error: "unable to parse Pokemon:\n- Pokemon/id must be string"

I expected this:

It would have been nice to get a more clear error like "Found Pokemon.id was a number, but expected it to be a string"

Is there a workaround?

No response

Anything else?

No response
