using nlohmann::basic_json::other_error = detail::other_error
This exception is thrown in case of errors that cannot be classified with the other exception types. Exceptions have ids 5xx.
name / id | example message | description
--- | --- | ---
json.exception.other_error.501 | unsuccessful: {"op":"test","path":"/baz", "value":"bar"} | A JSON Patch operation 'test' failed. The unsuccessful operation is also printed.
  See also - exception for the base class of the library exceptions - parse_error for exceptions indicating a parse error - invalid_iterator for exceptions indicating errors with iterators - type_error for exceptions indicating executing a member function with a wrong type - out_of_range for exceptions indicating access out of the defined range Example The following code shows how an `other_error` exception can be caught. 1 #include <iostream> 2 #include <nlohmann/json.hpp> 3 4 using json = nlohmann::json; 5 6 int main() 7 { 8 try 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; 28 } 29 } Output (play with this example online):
      message: [json.exception.other_error.501] unsuccessful: {"op":"test","path":"/best_biscuit/name","value":"Choco Leibniz"}
      exception id: 501
  The example code above can be translated with
      g++ -std=c++11 -Isingle_include doc/examples/other_error.cpp -o other_error
