Hi,
I'm using Poco 1.11.1 JSON module
I have to parse a JSON string and have the following error with JSON files

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

what(): Assertion violation

This is the json:

i can validate correctly using

https://jsonformatter.curiousconcept.com/#

This is the procedure to parse

Poco::JSON::Object::Ptr jsonToObj(std::string json)
{
    std::cout << "jsonToObj 1" << std::endl;
    Poco::JSON::Parser parser;
    std::cout << "jsonToObj 2" << std::endl;
    Poco::Dynamic::Var result = parser.parse(json);
    std::cout << "jsonToObj 3" << std::endl;
    parser.reset();
    std::cout << "jsonToObj 4" << std::endl;
    Poco::JSON::Object::Ptr pObject = result.extract<Poco::JSON::Object::Ptr>();
    std::cout << "jsonToObj " << std::endl;

    return pObject;
}
