Some mandatory parameters are missing ("source") to generate a URL for route "project_browser.browse".

Yeah - alpha7 removed the /admin/modules/browse route; you always need to pass a source plugin ID as well, for example /admin/modules/browse/drupalorg_jsonapi. But we did an incomplete job when we made that change, and therefore it is still possible to visit these defunct routes, which will cause the exception you got.

This will be fixed outright by 🐛 WSOD when using settings to limit sources to recipes Active , so tentatively closing this issue as a duplicate of that one.

I saw that issue https://www.drupal.org/project/project_browser/issues/3500024 🐛 WSOD when using settings to limit sources to recipes Active we fixed so I tried that patch https://git.drupalcode.org/project/project_browser/-/merge_requests/673 but it did not work for me so please re-open this for me.

Thanks

Still happening with 2.0.x-dev?

If so, can you provide clear steps to reproduce?

Bear in mind that /admin/modules/browse no longer exists, so you will get an error (probably a 404) if you try to visit it.

Everything is fine when I use 2.0.0-alpha6. 2.0.x-dev works okay as well.

When I do a simple composer update to 2.0.0-alpha7 or 2.0.0-alpha8 I get WSOD.

composer require 'drupal/project_browser:^2.0@alpha'

I think you have an outdated container. Can you try drush cr (or a full cache clear)?

Work happening on this issue ATM,

I will be updating Summary shortly,

In our case the issue occurred on sites using Project Browser in our dev config split. These were Drupal Core 10.4.1, with PHP 8.3, and many contrib modules installed.

ddev composer update -W

which ran fine and included the following

…
- Upgrading drupal/project_browser (2.0.0-alpha6 => 2.0.0-alpha8): Extracting archive. 
…

ddev drush cr
ddev launch
WSOD as soon as I launched with the reported error.

@timplunkett suggested the problem happened when admin_toolbar_tools module is installed. Once I uninstalled that module I was able to update to project_browser-2.2.0-alpha8

Summary updated

Same happening to me on a site with Drupal 10.4.2

Error appears on any route even not related to Project browser

This issue will probably surface on every Gin install if that's the case

OK, I guess this seems like it works as designed. Closing it out, but feel free to reopen if I've missed something.
