Random error when running in ios

[vishnuc]

What happened?

I keep getting this error when i use only react-native-google-mobile-ads

(NOBRIDGE) LOG AdMob initialized successfully
(NOBRIDGE) LOG Adapter statuses: [{"description": "<GADAdapterStatus: 0x6000017bb080; state = Ready>", "name": "GADMobileAds", "state": 1}]

I use below code

import Constants from "expo-constants";
import { Platform, View, Text } from "react-native";

// Define the type for mobileAds to handle potential undefined case
let mobileAds: any = undefined;
let BannerAd: any = undefined;
let BannerAdSize: any = undefined;

// Only load the module if we're not in Expo Go
if (Constants.executionEnvironment !== "storeClient") {
  // Using require instead of import for conditional loading
  const ads = require("react-native-google-mobile-ads");
  mobileAds = ads.default;
  BannerAd = ads.BannerAd;
  BannerAdSize = ads.BannerAdSize;
  TestIds = ads.TestIds;
}

export const initAdmob = async () => {
  console.log("Execution Environment:", Constants.executionEnvironment);
  console.log("Dev Environment", __DEV__);

  if (Constants.executionEnvironment !== "storeClient" && mobileAds) {
    try {
      const adapterStatuses = await mobileAds().initialize();
      console.log("AdMob initialized successfully");
      console.log("Adapter statuses:", adapterStatuses);
    } catch (error) {
      console.error("Failed to initialize AdMob:", error);
    }
  } else {
    console.log("Skipping AdMob initialization in Expo Go");
  }
};

// Banner Ad Component
import React, { useRef, useEffect } from "react";

const BANNER_AD_UNIT_ID = __DEV__
  ? (TestIds?.BANNER ?? "")
  : Platform.select({
      ios: "ca-app-pub-2399707265097616/6526811132",
      android: "ca-app-pub-2399707265097616/4989565851",
      default: "", // Fallback empty string for other platforms
    });

// Dummy Ad Component for development
const DummyAd = () => {
  return (
    <View className="h-[50px] w-full items-center justify-center border border-input bg-muted">
      <View className="text-muted-foreground">
        <Text className="text-sm text-muted-foreground">Ad Placeholder</Text>
      </View>
    </View>
  );
};

export const BannerAdComponent = () => {
  const bannerRef = useRef(null);

  if (Constants.executionEnvironment === "storeClient" || !BannerAd) {
    return <DummyAd />; // Return dummy ad in Expo Go or if BannerAd is not available
  }

  return (
    <View className="w-full items-center justify-center">
      <BannerAd
        ref={bannerRef}
        unitId={BANNER_AD_UNIT_ID}

      />
    </View>
  );
};

That doesn't look like an iOS crash trace to me, there is not enough information to localize a problem and look for a solution here.

Run the app from Xcode, watch the console and get the actual crash trace and paste it in here in between triple-backticks (so it's formatted well) and if there is a stack frame pointing to this module we can investigate

[vishnuc]

In Xcode I get below error

0x11f031140 - ProcessAssertion::acquireSync Failed to acquire RBS assertion 'XPCConnectionTerminationWatchdog' for process with PID=45388, error: (null)

@vishnuc I don't know what any one expects with regard to support or troubleshooting when next to zero information is provided. There's nothing really to go on here.

[vishnuc]

Hey I am sorry , But only when I use react-native-google-mobile-ads , maybe this issue in dev build

[mikehardy]

You are still not providing any information that could be useful to help locate the error

[vishnuc]

Hey am sorry , but please guide me how get useful information ? I run in xcode and pasted the warnings i received in console..ads are working fine , but this warnings keep popping up

[mikehardy]

If ads are working, I think there is nothing to be done. Have you searched around for the error message prior to posting? I just did so and If you search around for that message or similar ones you'll see that they are apparently outside of the control of the app or this module
