Redmine 5.0 on Debian Bookworm: “Tried to load unspecified class: ActionController::Parameters”

[albrechtd]

Summary

The plugin can be installed on Debian Bookworm (aka testing), but using it fails with error

ActionView::Template::Error (Tried to load unspecified class: ActionController::Parameters):

Description

The plugin can be installed, but any operation dealing with templates (i.e. creating a new ticket, trying to edit a template, …) produces errors as in the log snippet below, and an error page in the browser.

Please note that the database contents is actually a “cleaned” import from Redmine 4 (i.e. the table contents has been updated regarding the differences between Redmine 4 and 5, but the DB Schema is of course the original one from Redmine 5). As I had several other plugins installed on Redmine 4, the data produced by them is still in the (imported) database. However, for this test I removed all plugin folders (from usr/share/redmine/plugins) except for the issue templates, but did not remove related data from the database. I don't think this would make a difference, though.

Expected Results

Plugin should work as with Redmine 4 on Debian Buster.

Actual Results

See above.

Workaround

Unfortunately not…

Thank you for contributing to Redmine Issue Templates plugin!' first issue

[albrechtd]

I found a workaround (which may actually be the solution, see Redmine issue 37719 re. the background):

Edit the file /usr/share/redmine/config/application.rb, and add ActionController::Parameters to the array config.active_record.yaml_column_permitted_classes.

Now the plugin works with Redmine 5 on Bookworm…
