Description

The following is the JSON, which is valid while checking with the online parser at http://json.parser.online.fr/

[{ "op" : "add", "path" : "XYZL_ABCDE", "value" : {"appName" : "TST", "SNO" : [ 100, 101 ]}}]

JSONCPP reports parse error on Redhat enterprise linux on x86 platform. The error string reported by parse() is shown below

  • Line 1, Column 82
    Missing ',' or ']' in array declaration
    terminate called after throwing an instance of 'Json::LogicError'
    what(): in Json::Value::resolveReference(key, end): requires objectValue

If I convert the array values [100, 101] in the above Json string to ["100", "101"] the parse succeeds. Any help in resolving this will be much appreciated. Thanks in advance.

Research direction

Start by reproducing the supplied JSON with jsoncpp's parse() on RHEL x86, then inspect the reported Json::Value::resolveReference(key, end) path and the parser error around the numeric array. Done means the valid array [100, 101] parses without the missing-delimiter error or the subsequent LogicError.
