Detailed Description

exception indicating a parse error

This exception is thrown by the library when a parse error occurs. Parse errors can occur during the deserialization of JSON text, CBOR, MessagePack, as well as when using JSON Patch.

Member byte holds the byte index of the last read character in the input file.

Exceptions have ids 1xx.

name / id	example message	description
json.exception.parse_error.101	parse error at 2: unexpected end of input; expected string literal	This error indicates a syntax error while deserializing a JSON text. The error message describes that an unexpected token (character) was encountered, and the member byte indicates the error position.
json.exception.parse_error.102	parse error at 14: missing or wrong low surrogate	JSON uses the \uxxxx format to describe Unicode characters. Code points above above 0xFFFF are split into two \uxxxx entries ("surrogate pairs"). This error indicates that the surrogate pair is incomplete or contains an invalid code point.
json.exception.parse_error.103	parse error: code points above 0x10FFFF are invalid	Unicode supports code points up to 0x10FFFF. Code points above 0x10FFFF are invalid.
json.exception.parse_error.104	parse error: JSON patch must be an array of objects	RFC 6902 requires a JSON Patch document to be a JSON document that represents an array of objects.
json.exception.parse_error.105	parse error: operation must have string member 'op'	An operation of a JSON Patch document must contain exactly one "op" member, whose value indicates the operation to perform. Its value must be one of "add", "remove", "replace", "move", "copy", or "test"; other values are errors.
json.exception.parse_error.106	parse error: array index '01' must not begin with '0'	An array index in a JSON Pointer (RFC 6901) may be 0 or any number without a leading 0.
json.exception.parse_error.107	parse error: JSON pointer must be empty or begin with '/' - was: 'foo'	A JSON Pointer must be a Unicode string containing a sequence of zero or more reference tokens, each prefixed by a / character.
json.exception.parse_error.108	parse error: escape character '~' must be followed with '0' or '1'	In a JSON Pointer, only ~0 and ~1 are valid escape sequences.
json.exception.parse_error.109	parse error: array index 'one' is not a number	A JSON Pointer array index must be a number.
json.exception.parse_error.110	parse error at 1: cannot read 2 bytes from vector	When parsing CBOR or MessagePack, the byte vector ends before the complete value has been read.
json.exception.parse_error.112	parse error at 1: error reading CBOR; last byte: 0xF8	Not all types of CBOR or MessagePack are supported. This exception occurs if an unsupported byte was read.
json.exception.parse_error.113	parse error at 2: expected a CBOR string; last byte: 0x98	While parsing a map key, a value that is not a string has been read.
json.exception.parse_error.114	parse error: Unsupported BSON record type 0x0F	The parsing of the corresponding BSON record type is not implemented (yet).

Note

For an input with n bytes, 1 is the index of the first character and n+1 is the index of the terminating null byte or the end of file. This also holds true when reading a byte vector (CBOR or MessagePack).
