exception indicating access out of the defined range

This exception is thrown in case a library function is called on an input parameter that exceeds the expected range, for instance in case of array indices or nonexisting object keys.

Exceptions have ids 4xx.

name / id	example message	description
json.exception.out_of_range.401	array index 3 is out of range	The provided array index i is larger than size-1.
json.exception.out_of_range.402	array index '-' (3) is out of range	The special array index - in a JSON Pointer never describes a valid element of the array, but the index past the end. That is, it can only be used to add elements at this position, but not to read it.
json.exception.out_of_range.403	key 'foo' not found	The provided key was not found in the JSON object.
json.exception.out_of_range.404	unresolved reference token 'foo'	A reference token in a JSON Pointer could not be resolved.
json.exception.out_of_range.405	JSON pointer has no parent	The JSON Patch operations 'remove' and 'add' can not be applied to the root element of the JSON value.
json.exception.out_of_range.406	number overflow parsing '10E1000'	A parsed number could not be stored as without changing it to NaN or INF.
json.exception.out_of_range.407	number overflow serializing '9223372036854775808'	UBJSON and BSON only support integer numbers up to 9223372036854775807. (until version 3.8.0)
json.exception.out_of_range.408	excessive array size: 8658170730974374167	The size (following #) of an UBJSON array or object exceeds the maximal capacity.
json.exception.out_of_range.409	BSON key cannot contain code point U+0000 (at byte 2)	Key identifiers to be serialized to BSON cannot contain code point U+0000, since the key is stored as zero-terminated c-string
