Crash on iOS Device

[michitosh]

The App crashes on iOS when FileUpload Instance tries to start more then one payload at once.

If only one payload is started or if I wait 10 Secunds until I init the second payload everything works fine.
Uploader is set to {parallelUploadsLimit: 5}

Below I've added the log from XCode.
I verified that the Files are stored and can be accessed.

This is an example file path:
file:///var/mobile/Containers/Data/Application/54190526-4123-40BC-AC1C-80914BF94EEA/Library/files/my_folder/1619733997937.jpg

Hi @michitosh,

Could you provide more details on the iOS version and device used? And how the plugin has been initialized and is being used in the code? We might not be getting into this debug right now but a PR with the necessary fixes will be most welcome and greatly appreciated.

Thanks,
Azhar

Hi @azharbeebeejaun ,

Cordova v10.0.0
Cordova iOS v6.2.0
iPhone X iOS 14.5

The Plugin is initialized in the device ready listener:

`document.addEventListener('deviceready', function () {
uploader = FileTransferManager.init({
parallelUploadsLimit: 5
});
uploader.on('success', function (upload) {
uploader.removeUpload(upload.id, function () {
//upload aborted
}, function (err) {
//could abort the upload
});
});

[...]

});`

The payload is added like this:

db.executeSql('SELECT * FROM XXXX WHERE draft_id=?', [SQLiteId], function (rs) {
var payload = {
"id": rs.rows.item(i).id,
"filePath": rs.rows.item(i).imagepath,
"fileKey": "file",
"serverUrl": postlink + "api/" + api_version + "/Upload",
"showNotification": true,
"notificationTitle": language[lang].lang_upload_progress,
"headers": {
"X-ACTION": "media-upload",
"AUTHTOKEN": userdata.auth
},
"parameters": {
"gp_id": DraftId,
"fileName": uploadFileName
}
};
uploader.startUpload(payload);
}, function (error) {
console.log('UPDATE error: ' + error.message);
});

I've just got the same issue. The iOS version is the 16.1.1 on a iPhone 13 Pro Max. Here's the error and how is initialized and used.

Error:

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[App.AppDelegate backgroundCompletionBlock]: unrecognized selector sent to instance 0x280576600'

Init:

uploader = BackgroundUpload.init({
                callBack: event => {
                    console.log(event);
                    switch (event.state) {
                        case 'UPLOADING':
                            console.log('Still uploading')
                            break
                        case 'UPLOADED':
                            console.log('upload done')
                            break
                        case 'FAILED':
                            if (event.id) {
                                console.log("upload: " + event.id + " has failed");
                            } else {
                                console.error("uploader caught an error: " + event.error);
                            }
                    }

                    if (event.eventId) {
                        console.log('Event done and ACK')
                        uploader.acknowledgeEvent(event.eventId)
                    }
                }
            })

How is used:

for (const photo of photos) {
            const payload: FTMPayloadOptions = {
                id: uuidv4(),
                filePath: photo.filepath,
                fileKey: "file",
                serverUrl: serverUrl,
                notificationTitle: "Uploading images",
            };
            uploader.startUpload(payload);
        }

The upload works fine, but at the end, the error message is presented and the app freezes/crashes.

Hello @matheuscas ,

Can you send me your version of background upload you are using.

Hello @matheuscas,

You should install this version :
cordova plugin add @spoonconsulting/cordova-plugin-background-upload

Also make sure the version is 4.0.7, 1.1.0 is outdated.

[matheuscas]

Hey @zfir , one more information that maybe can help you, I believe. Here the steps:

• As soon as I press "Upload all" button to upload all photos I lock the phone
• Everything stays fine until I unlock the phone and get back to the app.
• After that, I get the above mentioned exception and the app crashes.

I hope that this helps you.

Hello @matheuscas,

You should install this version : cordova plugin add @spoonconsulting/cordova-plugin-background-upload

Also make sure the version is 4.0.7, 1.1.0 is outdated.

Hello @matheuscas,

Can you try this and let me know if you have the same error

[matheuscas]

@zfir Problem solved. Since I'm using Capacitor, I npm installed @spoonconsulting/cordova-plugin-background-uploa and cordova-plugin-file rather than adding it using cordova command. The only errors showed after unlocking the phone were below, but they didn't crash the app. Thank you for your help and for your work on this plugin.
