Fatal error when enabling the new experimental sidebar navigation

I also tried enabling the new experimental menu setting after updating Gin to 8.x-3.0-rc7 and Gin_Toolbar to 1.0.0-rc4 . However, the logs show a different error :

Error: Class "Drupal\block_content\Entity\BlockContentType" not found in Drupal\gin\GinNavigation->getNavigationCreateMenuItems() (line 88 of /var/www/html/web/themes/contrib/gin/src/GinNavigation.php).

I'm not sure if this is a Gin or Gin_Toolbar problem...

Moving this to the Gin issue queue as the code comes from Gin.

@bramvandenbulcke @Dimiter can you verify that the MR solves your issues? TY!

Thank you saschaeggi for working on this. I found this issue today and the MR didn't solve the issue. I've attached a patch and diff of my changes that worked.

To test

• Install Drupal minimal profile
• Install Toolbar module
• Install Gin theme
• Set Gin as Administration theme
• Configure Gin to use "New Drupal Navigation, Test integration"

@saschaeggi the MR shows the same error but patch 3394085-09 is working fine. The icons in the experimental sidebar look a bit weird but the functionality is working fine with this patch.

Patch#9 is working for me (minimal profile). And yes, I can confirm that the Icons are missing - only the fallback "icon" applies:

.toolbar-link--has-icon {
  --icon: icon("fallback"); /* Default icon, aka --basic */
}

Well then let's proceed with this patch then 👍

The icons in the experimental sidebar look a bit weird but the functionality is working fine with this patch.

Not sure what you mean with that? Are the icons broken?

@gnuschichten can you try to clear the cache - might be cache related.

@saschaeggi I cleared both the Drupal cache and the images cached in the browser. Result: Menu Icons
