6 int main()
7 {

9  {
10  // executing a failing JSON Patch operation
11  json value = R"({
12  "best_biscuit": {
13  "name": "Oreo"
14  }
15  })"_json;
16  json patch = R"([{
17  "op": "test",
18  "path": "/best_biscuit/name",
19  "value": "Choco Leibniz"
20  }])"_json;
21  value.patch(patch);
22  }
23  catch (json::other_error& e)
24  {
25  // output exception information
26  std::cout << "message: " << e.what() << '\n'
27  << "exception id: " << e.id << std::endl;
