It would be very helpful to get the path in the json provided to where the error is coming from.
e.g. when I pass a number where there should be an object, I get the error: "applyeach not applicable for JSON.LazyValue{String} with JSON type = JSONTypes.NUMBER".
(if I pass "percent": 0.1 instead of "percent": {"value": 0.1})
It would be much better, if a path to the error is added, like "applyeach not applicable for JSON.LazyValue{String} with JSON type = JSONTypes.NUMBER at /path/to/percent ".
Thanks!
