Help with error: no matching function for call to 'unescape'

[rnikander]

I get this compiler error but it doesn't refer to my code so I don't know what is causing it. All I do is include the file. I don't even use the json types yet.

Here are the first few lines of LogImpl.cc, referred to by the error message.

module;

#include <ranges>
#include <nlohmann/json.hpp>
#include <iostream>

Here is the error:

In file included from /Common/Common/LogImpl.cc:4:

    return nlohmann::json::json_pointer(std::string(s, n));

Any hints about what is going on?

Could be an issue with Clang. I'm using the HEAD from git, not a release.
