+### Error handling
+
+If any error occurs during the request flight, such as an unsuccessful response code, `PapyrusError` will be thrown. You can use it to access failed request and response (if present).
+```swift
+@GET("/user")
+func getUser() async throws -> User
+
+do {
+    let user = try await users.getUser()
+} catch {
+    if let error = error as? PapyrusError {
+        print("Error making request \(error.request). Response was: \(error.response)")
+    }
