Hi, I am unable to trigger the notification using WebService. I followed the following steps: 1. Replace all required placeholders in WebService. Build and run successfully. I see the following messages on launch: - **[WARNING] No custom working directory set for this scheme, using /Users/my3vshenoy/Library/Developer/Xcode/DerivedData/PushWebService-cfibixdtcoibqabodusrwdbzblof/Build/Products/Debug** **[NOTICE] Server starting on [http://0.0.0.0:8080](http://0.0.0.0:8080)** **2022-05-23 22:34:03.491939-0400 Run[77788:797760] [si\_destination\_compare] send failed: Invalid argument** **2022-05-23 22:34:03.492001-0400 Run[77788:797760] [si\_destination\_compare] send failed: Undefined error: 0** 1. Then my App launches, I do see a console message with requestId, so the communication is happening 2. Tried using the Push Notifications Tester to verify if the keys were the issue. No, I successfully get the push on my device through it. Please help! Thanks ---
