Expo iOS build crashes when building internal prod build but not with expo run:ios

My build crashes when running with

eas build --profile production --platform ios

But not with expo run:ios

eas.json:

{
  "cli": {
    "version": ">= 0.60.0",
    "appVersionSource": "remote"
  },
  "build": {
    "local": {
      "developmentClient": false,
      "env": {
        "APP_ENV": "dev"
      },
      "ios": {
        "simulator": true
      }
    },
    "development": {
      "developmentClient": true,
      "distribution": "internal",
      "env": {
        "APP_ENV": "dev"
      }
    },
    "preview": {
      "developmentClient": false,
      "distribution": "internal",
      "env": {
        "APP_ENV": "prod"
      },
      "ios": {
        "image": "macos-sequoia-15.3-xcode-16.2"
      }
    },
    "production": {
      "developmentClient": false,
      "env": {
        "APP_ENV": "prod"
      },
      "autoIncrement": true,
      "ios": {
        "image": "macos-sequoia-15.3-xcode-16.2",
        "simulator": true

      }
    }
  }
}

What could the issue be?

The issue was that the production environment variables were not set up in my Expo account. I set them here and the crash resolved.
