fix: say which value failed to parse and why references could not be resolved - #54
Merged
Merged
Conversation
…resolved - Integer, long and bool scalar errors now include the value and the reason (not a whole number vs. out of range) and the location of the field. Schema integer fields used a catch-all that reported every failure as "The value is out of range"; they now use the same helper. - A reference whose document cannot be read now reports the underlying error, and a failed reference is no longer reported twice (once with the specific reason, then again as "Unable to deserialize reference"). - JsonPointer.Find no longer swallows exceptions. It also returned the scalar it walked into for pointers such as /info/title/nested instead of null. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

…ne integer sign Parse JSON pointer array tokens with NumberStyles.None and the invariant culture, so tokens such as "-0", "+0" or " 0" no longer resolve to an element. When explaining an invalid integer, strip at most one leading sign so values such as "+-1" are reported as malformed rather than out of range. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

…oleans
Array tokens with a leading zero ("01", "00") no longer resolve, per RFC 6901.
The uniqueItems, readOnly, writeOnly and deprecated schema fields now use
GetBooleanValue, so an invalid value produces a diagnostic naming the value
instead of an unhandled FormatException.

Several reader errors hid what actually went wrong:
maxLength,minItems, …) used a catch-all that reported every failure asThe value is out of range., includingabcand1.5.Value could not parse to integer.without the value or the field location.Unable to deserialize referencewithout the cause (barecatch), and any failed reference was reported twice: once with the specific reason, then again generically.JsonPointer.Findswallowed all exceptions, and for a pointer that walks into a scalar (/info/title/nested) it returned the scalar instead ofnull.Change
Value 'abc' could not parse to integer. Expected a whole number.orValue '99999999999' could not parse to integer. It must be between -2147483648 and 2147483647., with the field's pointer. Schema integer fields use the same helper. The existing "could not parse to …" wording is kept.JsonPointer.Findchecks array bounds and node kinds instead of catching exceptions.Tests
