The following code shows how a `other_error` exception can be caught.

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

    using json = nlohmann::json;

    int main()
    {
        try
        {
            // executing a failing JSON Patch operation
            json value = R"({
                "best_biscuit": {
                    "name": "Oreo"
                }
            })"_json;
            json patch = R"([{
                "op": "test",
                "path": "/best_biscuit/name",
                "value": "Choco Leibniz"
            }])"_json;
            value.patch(patch);
        }
        catch (json::other_error& e)
        {
            // output exception information
            std::cout << "message: " << e.what() << '\n'
                      << "exception id: " << e.id << std::endl;
        }
    }

Output:

    message: [json.exception.other_error.501] unsuccessful: {"op":"test","path":"/best_biscuit/name","value":"Choco Leibniz"}
