No "New Poll" button visible / json_decode error in the log

⚠️ This issue respects the following points: ⚠️

• This is a bug, not a question or a configuration/webserver/proxy issue.
• This issue is not already reported on Github (I've searched it).
• I agree to follow Nextcloud's Code of Conduct.

What went wrong, what did you observe?

After upgrading to v28, somehow my Polls app stopped working. Whenever I enter the Polls app, the "New poll" button in the left sidebar is missing. Users can't see any polls.

The admin can see the polls through the "Administration" menu item.

At the same time, every time a user enters the App, there is the following error in the log:

[index] Error: json_decode(): Argument #1 ($json) must be of type string, null given in file '/var/www/html/apps/polls/lib/Db/Preferences.php' line 71
	GET /apps/polls/polls?time=1706647856873
	from xx.xxx.xx.xx by moritz at 30.01.2024, 21:50:56

What did you expect, how polls should behave instead?

• Polls should be visible
• "New Poll" button should be visible

What steps does it need to replay this bug?

Not sure how to recreate this. Must have happened during the upgrade from 27 to 28.

See #3216, fixed in #3219 and targeted for version 6.1.0.

As a quick fix the user has to open his Polls preferences (lover left corner) once and change a setting.
