Expo iOS build : ERROR ITMS-90085 when submitting with Transporter app

Question

i built an React Native app with expo which is now online in the Apple App Store. I've tweaked it a bit and came with a new version that i'm trying to upload with Transporter (just like i did the first time). But this time Transporter is giving me this error message :

ERROR ITMS-90085: "No architectures in the binary. Lipo failed to detect any architectures in the bundle executable."

here is my app.js :

{
  "expo": {
    "name": "Appname",
    "slug": "appname",
    "version": "0.2",
    "orientation": "portrait",
    "icon": "./assets/icon.png",
    "splash": {
      "image": "./assets/splash.png",
      "resizeMode": "cover",
      "backgroundColor": "#0042DA"
    },
    "userInterfaceStyle": "light",
    "updates": {
      "fallbackToCacheTimeout": 0
    },
    "assetBundlePatterns": ["**/*"],
    "ios": {
      "supportsTablet": true,
      "bundleIdentifier": "com.name.name",
      "buildNumber": "0.2.0",
      "infoPlist": {
        "NSCameraUsageDescription": "This app uses the camera to take pictures and document the work achieved by the technician."
      }
    },
    "android": {
      "package": "com.name.name",
      "versionCode": 3,
      "permissions":["CAMERA", "CAMERA_ROLL"]
    },
    "web": {
      "favicon": "./assets/favicon.png"
    }
  }
}

I've already built it twice... Any idea how i can solve this? Best
