Bug description

After fresh install of Nextcloud Server 25, "Applications" page does not load properly. Log page shows the following error:

[index] Erreur: Exception: OC\App\PlatformRepository::normalizeVersion(): Argument #1 ($version) must be of type string, null given, called in /home/qamydtds/drive/lib/private/App/PlatformRepository.php on line 53 in file '/home/qamydtds/drive/lib/private/App/PlatformRepository.php' line 148 at <>

   OC\AppFramework\App::main()
2. /home/qamydtds/drive/lib/base.php line 1047
   OC\Route\Router->match()
3. /home/qamydtds/drive/index.php line 36

GET /index.php/settings/apps/list
from 81.251.75.201 by ******************** at 2022-10-21T01:57:46+00:00

Seems to be a problem with the way the exception is handled in the following code:

			$ext = new \ReflectionExtension($name);
			try {
				$prettyVersion = $ext->getVersion();
				$prettyVersion = $this->normalizeVersion($prettyVersion);
			} catch (\UnexpectedValueException $e) {
				$prettyVersion = '0';
				$prettyVersion = $this->normalizeVersion($prettyVersion);
			}

Steps to reproduce

1. Do a fresh install using the web installer
2. Go the the "Applications" page

Expected behavior

Applications page should load list of installed apps.

Additional info

Just going to mention that the error was reproducible with php 7.4 and 8.1 too.

It is likely a duplicate of issue #34690, just encountered from different steps. Probably easier to reproduce with those listed here though.

[tflidd]

There was a suggestion for a fix on the forum (probably just a dirty workaround by disabling type hints):
https://help.nextcloud.com/t/apps-page-error-after-update-to-25/148083

[Skatox]

I'm having the same problem. I disabled types in the method's arguments and works.

@come-nc can you have a look ?

Hello @Skatox
Since you seem comfortable with modifying source files, could you try https://github.com/nextcloud/server/pull/34937/files and confirm it fixes the problem?

[Nyalnara]

Just reinstalled on my dev-env (because the one where I originally had the problem needed to work so installed a 24), web installer now pull version 25.0.1 which doesn't encounter the problem.
Will see about installing 25.0.0 from archive to reproduce and give feedback on pull linked above this week-end.

Upgraded from 24.0.7 to 25.0.1 = same issue
