I am developing an app for my home and I was planning to control my smart home plug with it. So I decided to create two shortcuts: the first one to turn it on, the second one to turn it off. For this, I created an AppIntent and an AppShortcut file:

//  AppIntent.swift
//  Runner

import AppIntents
import Foundation

class MerossPostClass{
    
    var request: URLRequest
    var power_state: String
    
    public init(power_state: String) {
        self.power_state = power_state
        let url = URL(string: "myurl")!
        var request = URLRequest(url: url)
        request.httpMethod = "POST"
        struct Message: Encodable {
            let device_type: String
            let power_state: String
            let channel: Int
        }
        let message = Message(
            device_type: "mss425f",
            power_state: power_state,
            channel: 4
        )
        let data = try! JSONEncoder().encode(message)
        request.httpBody = data
        request.setValue(
            "application/json",
            forHTTPHeaderField: "Content-Type"
        )
        self.request = request
    }

    public func post(){
         let task = URLSession.shared.dataTask(with: self.request) { data, response, error in
          let statusCode = (response as! HTTPURLResponse).statusCode
          
          if statusCode == 200 {
              print("SUCCESS")
          } else {
              print("FAILURE")
          }
      }
      task.resume()
    }
}

var activateMeross = MerossPostClass(power_state: "ON")
var deactivateMeross = MerossPostClass(power_state: "OFF")

@available(iOS 17, *)
struct ActivateMagSafeIntent: AppIntent {
  static let title: LocalizedStringResource = "Activate MagSafe"

  func perform() async throws -> some IntentResult {
    activateMeross.post()
    return .result()
  }
}

@available(iOS 17, *)
struct DeactivateMagSafeIntent: AppIntent {
  static let title: LocalizedStringResource = "Deactivate MagSafe"
      
    func perform() async throws -> some IntentResult {
      deactivateMeross.post()
      return .result()
    }
}

//
//  AppShortcut.swift
//  Runner

import Foundation
import AppIntents

@available(iOS 17, *)
struct ActivateMagSafeShortcuts: AppShortcutsProvider {
  @AppShortcutsBuilder
  static var appShortcuts: [AppShortcut] {
    AppShortcut(
      intent: ActivateMagSafeIntent(),
      phrases: ["Activate MagSafe"]
    )
    AppShortcut(
      intent: DeactivateMagSafeIntent(),
      phrases: ["Deactivate MagSafe"]
    )
  }
}

With this Code I can add the shortcuts to the shortcuts app.

Problem

As long as my device is attached to the debugger, everything is working just fine and I am able to control my smart plug with the shortcuts. But after I detached my phone from the debugger, the shortcuts are only working every second run. After every other run, I get an iOS error message like 'Couldn't Communicate with a helper application' or 'App was terminated unexpectedly'. Is there anybody who has been facing the same issue or has any idea why this is happening?

Thanks in advance!
