JSON Parse Out of Range Error

[jeffmorr]

Hi all,

I am getting an out of range error when I'm trying to parse my json file and I'm not sure why.

My json file

[
    {
        "TableType" : "Random",
        "TableName" : "CurrencyTable",
        "TableEntryCollection" : [
            {
                "EntryType" : "Item",
                "EntryName" : "platinum",
                "MinDrops" : 1,
                "MaxDrops" : 10,
                "SelectionWeight" : 0.25
            },

Can you please post the description of the exception (what())?

[jeffmorr]

I get:
Unhandled exception at 0x00007FFCAF36A388 in Driver.exe: Microsoft C++ exception: nlohmann::detail::parse_error at memory location 0x0000007C0B33E310. occurred

from this function

bool parse_error(std::size_t /*unused*/, const std::string& /*unused*/,
                     const detail::exception& ex)
    {
        errored = true;
        if (allow_exceptions)
        {
            // determine the proper exception type from the id
            switch ((ex.id / 100) % 100)
            {
                case 1:
                    JSON_THROW(*static_cast<const detail::parse_error*>(&ex));
                case 4:
                    JSON_THROW(*static_cast<const detail::out_of_range*>(&ex)); //Exception is thrown here!
                // LCOV_EXCL_START
                case 2:
                    JSON_THROW(*static_cast<const detail::invalid_iterator*>(&ex));
                case 3:
                    JSON_THROW(*static_cast<const detail::type_error*>(&ex));
                case 5:
                    JSON_THROW(*static_cast<const detail::other_error*>(&ex));
                default:
                    assert(false);
                    // LCOV_EXCL_STOP
            }
        }
        return false;
    }

[nlohmann]

Can you catch the exception and print what(), please?

[Meqolo]

How do i do that? I tried catching the exception but it still crashed rather than printing anything

[nlohmann]

Like this:

try
{
    // put here whatever code you call where the exception is triggered
}
catch (std::exception& e)
{
    std::cerr << e.what() << std::endl;
}

[Meqolo]

Oh, just realised that it's cutting bits of it off

[nlohmann]

This is not the library's fault - please check if the input you parse is proper JSON.

[Meqolo]

Oh, I was also on the wrong issue, sorry.
