+Example
+
+The following code shows how a `other_error` exception can be caught.
+
+```
+#include <iostream>
+#include <nlohmann/json.hpp>
+
+using json = nlohmann::json;
+using namespace nlohmann::literals;
+
+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 (const 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"}
+exception id: 501
+```
