Failed to save session while using PWA and enabled save tab groups

[DannyDeLoach]

Tab Session Manager has stopped automatically saving sessions as set in the settings. Also, when I click the 'Save' button to manually save the current session, I get the error, "Failed to save session".

Steps to reproduce

1. Set TSM to automatically save sessions (e.g. every 30 minutes, when a window is closed, etc.)
2. or
3. Click 'Save'

Expected result

1. Sessions will be automatically saved as set in settings
2. or
3. The current session will be saved when the 'Save' button is clicked

Actual result

1. No sessions are being automatically saved
2. Clicking the 'Save' button gives the error, "Failed to save session".

Here is a screenshot of the error I receive, when I click the 'Save' button:

I have enabled debug mode, but I do not know how to access and share the logs

Platform information

• Platform (OS): Windows 10
• Version of browser: Chrome Version 100.0.4896.88

Additional context

I removed the TSM extension from Chrome and deleted any of the TSM folders in the Chrome directory. I restarted my computer and re-installed TSM. The problem persists.

With Firefox the addon is nor saving manually nor automatically. It doesn't show any error either, it's been like that for some time now I just noticed.

Confirmed on Kiwi 101.0.4951.40 on fully updated stock Android 11 on both a Samsung Galaxy Tab A8, a Samsung Galaxy Tab A 10.4" 2020, and a Moto G Power (8th gen). I noticed it when I had to replace my old Samsung tablet and was backing up settings. The last saved sessions were from 2021. Supposedly, I exported 23 sessions from my old tablet, but only 22 show up after importing them. I lost about 6 months of data. I did try to enable cloud save, but nothing happens. Manual saves give the error OP listed. When I just thought to look at my Moto, the sessions listed when I first switched from Firefox to Kiwi are missing as well - no sessions appear, even though autobackups are enabled on both devices.

I did some more troubleshooting and discovered a pivotal piece of information.

If no 'web apps' are open, TSM works as expected. What I mean by 'web app', is when I open a web page, select 'More tools', 'Create shortcut', 'Open as window' and create a desktop shortcut for opening the web page as a 'web app'. If I open any of the 'web apps' I have created, then TSM exhibits the behavior described in my original post (i.e. it no longer automatically saves sessions and I can no longer manually save a session). If I close the 'web app', then TSM saves sessions as expected.

I would like to continue using 'web apps'. I would also like to use TSM. TSM is a great extension. I hope the author of the extension or someone with knowledge of how it works can help me figure out how to use TSM while I am also using 'web apps'.

@DannyDeLoach Please change issue title to reflect that it only happens when 'web apps'(PWAs?) are open.

Also just a note, it works fine for me on current latest Firefox 104.0.1(on Windows 11) and has always been fine(past few 4-5 years). I have over 1700 saved sessions, with each with tabs ranging from 20-80 tabs with huge variety and regularly use it. Not sure if I use any Web Apps.

Except @1024mb, everyone here seems to have issues with Chromium browsers only. I hope @1024mb can add their specific OS and browser versions.

Oops, forgot to update here, I don't know what the problem was on my end but uninstalling and reinstalling the addon fixed everything.
