## Problem to solve Creating a new Wiki page from the UI requires the content of the page to exist while creating the page via the command line does not. ## Proposal Make the Wiki page content field optional when creating a new page. We should still prevent the value from being `nil` but an empty string `""` should be acceptable. ## Documentation ## Testing --- https://sentry.gitlab.net/gitlab/gitlabcom/issues/1637330/?referrer=gitlab_plugin ``` WikiPage::Meta::WikiPageInvalid: WikiPage::Meta::WikiPageInvalid (105 additional frame(s) were not displayed) ... wiki_pages/event_create_service.rb:16:in `block in execute' wiki_page_meta = WikiPage::Meta.find_or_create(slug, page) gitlab/metrics/instrumentation.rb:161:in `find_or_create' .measure { super } gitlab/metrics/method_call.rb:36:in `measure' retval = yield gitlab/metrics/instrumentation.rb:161:in `block in find_or_create' .measure { super } wiki_page/meta.rb:38:in `find_or_create' raise WikiPageInvalid unless wiki_page.valid?
