Redmine

Hello,
i had a issue with projects tree. i found a 'solution' in this forum to rebuild the tree:

ruby bin/rails runner 'Project.rebuild_tree!' RAILS_ENV=production
ruby bin/rails runner 'Issue.rebuild_tree!' RAILS_ENV=production

now projects tree a re fine, but when i would like to enter in the project-issue page, i have an error:
