May I ask where 961c151d2e87f2686a955a9be24d316f1362bf21 comes from in this error message? is it a SHA1 of something? ta!

json/include/nlohmann/json.hpp

Line 519 in 5d27543

JSON_THROW(other_error::create(500, "961c151d2e87f2686a955a9be24d316f1362bf21 3.11.2", nullptr)); // LCOV_EXCL_LINE

[nlohmann]

It's

echo "JSON for Modern C++" | sha1sum
