[Bug]: iOS Crash when invoking offlinemanager.createPack() when there Token not set
Mapbox Implementation
Mapbox
Mapbox Version
default
React Native Version
0.76.9
Platform
iOS
@rnmapbox/maps version
10.1.33
Standalone component to reproduce
The below code works fine when the device has internet connection. If I switch the wifi off, there is a fatal crash when trying to download. Attached is the crash report from the simulator, but it crashes on physical device as well.
const OFFLINE_BOUNDS = {
west: 8.0,
south: 40.0,
east: 24.0,
north: 50.0,
};
export const downloadOfflineMap = async (
onStateChange: (downloadProgress: DownloadProgress) => void,
): Promise<void> => {
try {
// Check if offline manager is available
if (!Mapbox.offlineManager) {
console.error('Offline manager not available');
Alert.alert('Error', 'Map download is not available on this device');
onStateChange({state: DownloadState.ERROR, progress: 0});
return;
}
const currentState = await checkOfflineMapStatus();
if (currentState === DownloadState.DOWNLOADED) {
Alert.alert('Info', 'Offline map is already downloaded');
onStateChange({state: DownloadState.DOWNLOADED, progress: 100});
return;
}
onStateChange({state: DownloadState.DOWNLOADING, progress: 0});
const errorListener = (_region: any, err: object) => {
console.error('Offline pack error:', err);
Alert.alert('Error', 'Failed to download offline map');
onStateChange({state: DownloadState.ERROR, progress: 0});
};
const progressListener = (_region: any, progress: any) => {
try {
const percentage = Math.round(progress.percentage);
const state =
percentage === 100
? DownloadState.DOWNLOADED
: DownloadState.DOWNLOADING;
console.log(`Download progress: ${percentage}%`);
onStateChange({
state,
progress: percentage,
});
} catch (error) {
console.error('Error in progress listener:', error);
}
};
// Attention: The MapBox API limits offlinepacks to 750 Tiles.
// The current bounds and zoom level fit it, if you change them they
// might break
try {
await Mapbox.offlineManager.createPack(
{
name: mapName,
styleURL: Mapbox.StyleURL.Outdoors,
bounds: [
[OFFLINE_BOUNDS.east, OFFLINE_BOUNDS.north],
[OFFLINE_BOUNDS.west, OFFLINE_BOUNDS.south],
],
minZoom: 5,
maxZoom: 10,
},
progressListener,
errorListener,
);
} catch (createPackError) {
console.error('Error creating offline pack:', createPackError);
Alert.alert('Error', 'Failed to download offline map');
onStateChange({state: DownloadState.ERROR, progress: 0});
}
} catch (error) {
console.error('Error downloading offline map:', error);
Alert.alert('Error', 'Failed to download offline map');
onStateChange({state: DownloadState.ERROR, progress: 0});
}
};

why would you like to use createPack when you are offline? that doesn't make any sense, you should use something like @react-native-community/netinfo or a native module if you prefer to add if offline don't execute the code
Correction it is not a problem of connectivity. The crash only happens if MapBox.setAccessToken was not called before the function. When adding a map component and not setting the Access Token there is a error message and no crash. When downloading maps without token there is no error message and a hard crash.
It's not nice, we welcome a fix. But not something we plan to address in near future
