uint64_t being converted to int64_t in to_json

[adlai-shawareb]

Description

I am getting this runtime error:

Error converting JSON to BSON ([json.exception.out_of_range.407] integer number 18446744073701195776 cannot be represented by BSON as it does not fit int64

If I comment out use of the uint64_t value in to_json, and from_json, I don't get the error.

This appears to be very similar to Issue #4236, but not sure if it is the same.

If it is the same issue, do we know when 3.11.4 will be released?

Reproduction steps

This code will reproduce it:

uint64_t m_Data0 = 0;

inline void to_json( nlohmann::json& j, const Info& cInfo )
{
    j = nlohmann::json{ 
           { "Data0", cInfo.m_Data0 } };

Expected vs. actual results

I expect to_json to bring the uint64_t into the json object as a uint64_t.
