I'm fairly new to Drupal, the inside settings are quite easily to understand for me but when it gets to error fixing I'm kind getting stuck sometimes.

For a project I've installed the Open Social platform as my Drupal, which is working fine but a couple bugs and things for me to find out. I wanted a file browser as a Knowledge Base into my site so I've installed the FileBrowser module.

Now when I want to specify (open social) group rights to a file browser node, so only that group can look into this file browser, I get the following error and I cannot seem to find out where to solve it:

Uncaught PHP Exception Drupal\\Component\\Plugin\\Exception\\PluginNotFoundException: Plugin ID 'group_node:dir_listing' was not found.

Could anyone point me into the right direction?

  • Did you look at the backtrace information which code is trying to load the non-existing plugin?

It looks like the error is coming from a missing plugin provided by the group_node module, which if I recall ships with the Group module. Try re-downloading that module to your codebase, and clearing your cache. If that doesn't work, uninstall the group_node module.

  • Shamefully when I overwrite the module with a fresh downloaded one, it removes the entire option to be able to add group permissions so it seems like I'm going to have to find the problem in the code.

  • You probably have to enable the content type in the group settings.
