Argument #9 ($kernel) must be of type ?

I applied MR !41 and the error is gone.

Thanks!

This fixed the theme for me in Drupal core 10.3.0. Please commit.

Just upgrades a small site to drupal 10.3.0
I am using Bootstrap 8.x-3.30 as a base theme.

The result is WSOD

Is there a new release coming?

With release of 10.3.0 this issue became critical show stopper. Could we have it released ASAP please?

Thanks!

I experience the same with Drupal 10.3.0. The new release is needed immediately.

Same issue. Updated Drupal site from 10.1.8 to 10.3 today.

Because we do not get the new release, I generated this patch file.

Had the same issue with 10.3.0 Drupal core release.
However, the patch from #10 fixed it for me. Thanks.

Well, that was quick!

All is well.

Thankyou

Full release coming soon. I'm checking other issues to see if there is anything else that should go in the release.

Thank you all for the quick turnaround. I rolled back to 10.2.7 for now.

Automatically closed - issue fixed for 2 weeks with no activity.

I was getting the "Argument #9 ($kernel) must be of type" error after updating to Drupal 10.3.1, and it was resolved after updating Bootstrap to 3.31, except now the update.php page does not load. The database did update with Drush but the update.php page does not load even after clearing and rebuilding caches. All other admin and site pages I have checked seem to work.

The log now shows "Argument #2 must be of type array . . ."

Here is the full output:

I have the same issue as #19. Managed to get update script to run by removing block--system-menu-block--main.html.twig and block--system-menu-block--account.html.twig files.

Facing this issue. I assume the fix is available from version >=3.31.

Updating bootstrap worked for me after updating core to 10.3.

- "drupal/bootstrap": "^3.29",
+ "drupal/bootstrap": "^3.32",
