Unable to install plugin in Redmine 6.0.1.stable.

[Sudro]

When trying to install the plugin according to the instructions, a problem occurs.

I work with bitnami/redmine (deployed via Helm (in k8s)).

Here is a link to helm bitnami/redmine: https://artifacthub.io/packages/helm/bitnami/redmine

At the very beginning, I execute the command /opt/bitnami/redmine/plugins in the directory:
git clone https://github.com/alexbevi/redmine_knowledgebase.git

I go to the /opt/bitnami/redmine directory, log in as the redmine user and do the following:
Turning off freezing:
bundle config set frozen false

I install gems using this command:
bundle install
Here is the result:

Bundle complete! 48 Gemfile dependencies, 91 gems now installed.

After this I try to migrate:
bundle exec rake redmine:plugins:migrate NAME=redmine_knowledgebase RAILS_ENV=production
Here is the result:

I couldn't figure out what the error was.
I did all this in the /opt/bitnami/redmine directory.

You can try my fork

git clone https://github.com/yzzy/redmine_knowledgebase.git

Though I didn't test it with Redmine 6, my fork has difference exactly in the file with error in question.
