Issue with backup. Contacts and SMS not backed up.

[soplaris]

Hello,
I'm trying to back up my Samsung A21S with this script. I got everything started but encountered problems while backing up.
Here is the command-line output (german):

Exporting contacts (as vCard), call logs as well as SMS messages (as CSV).
adb: error: failed to stat remote object '/storage/emulated/0/open-android-backup-temp/.': No such file or directory
Errors occurred while backing up . - this file (or multiple files) might've been ignored.
mv: der Aufruf von stat für './backup-tmp/open-android-backup-temp/open-android-backup-contact*.vcf' ist nicht möglich: Datei oder Verzeichnis nicht gefunden
No contacts found on device - ignoring.
mv: der Aufruf von stat für './backup-tmp/open-android-backup-temp/SMS_Messages.csv' ist nicht möglich: Datei oder Verzeichnis nicht gefunden

Maybe someone can tell me how it will work. Doesn't seem to be a great problem, as I expect.

Thanks

Before this error occurs, the script asks you to press a button on your device to start exporting contacts and other data. Could you please make sure you've done that?

[soplaris]

I've done that as far as I can remember, but after the app for that purpose installs nothing is done. Only the permissions can be set and I have set them.

Same here:

Starting: Intent { cmp=mrrfv.backup.companion/.MainActivity }
The companion app has been opened on your device. Please press the 'Export Data' button - this will export contacts/messages to internal storage, allowing this script to back them up. When this is complete, press Enter to continue.

Before this error occurs, the script asks you to press a button on your device to start exporting contacts and other data. Could you please make sure you've done that?

I did!

I tried tar and adb both.

Device: Ulefone Armor x10 Pro
PC: Kubuntu 24.04.

Does anyone have an idea how to solve this problem, or do I have to accept that in case of losing or braking my phone nothing is backed up. Where are the writers of this program?

[soplaris]

I'm sorry! To solve this problem you have to give the companion app permissions on your phone. After this contacts, call logs and sms can be exported and the program continues to back up your device.
Sorry and thanks for this program.

Same thing happened to me but I finally figured it out. After hitting the "Export Data" button, I got an "Allow" button which sent me to the "Allow access to manage all files" slider. After sliding that, I hit the back button and waited. I got two more "Allow" buttons after about 5 seconds. I had never seen those before, probably because I pushed enter too quickly on my PC. Hitting those last two "Allow" buttons seems to have gotten it to work.

I have a different problem with the same result in the title: the companion app doesn't open up at all on the phone and the script doesn't throw any errors (e.g., it says the app was installed). Phone was unlocked and the rest of the backup proceeds correctly.
Any ideas?
