undefined method error of `NoMethodError in Decidim::Assemblies::Assemblies#show` about decidim

To investigate the cause, I added the following logging:

diff --git a/decidim-core/app/cells/decidim/content_blocks/participatory_space_metadata_cell.rb b/decidim-core/app/cells/decidim/content_blocks/participatory_space_metadata_cell.rb

         metadata_items.filter_map do |item|
           next if (value = translated_attribute(presented_space.send(item))).blank?
 

and it displayed like this:

00:19:09 web.1         | presented_space: Decidim::AssemblyPresenter, Decidim::Assemblies::ContentBlocks::MetadataCell

So I guess it's a problem of Decidim::Assemblies::ContentBlocks::MetadataCell.
