# この一文をinit.rbの代わりに差し込む
# prepend でOKな場合と、includeでOKな場合とがちょっとわからないので検証しながら
IssuesHelper.prepend(FullTextSearch::Hooks::SimilarIssuesHelper)

init.rb での　Helperへのincludeをやめる、もしくはprependにする。
まずはコメントアウト。

IssuesHelper.include(FullTextSearch::Hooks::SimilarIssuesHelper) のところが一番可能性ありなので。。

上記のようにやってみましたが、500エラーのままで、ログも変わりなかったです

了解です！

redmine_persist_wfmtを維持したまま、full_text_searchの利用が出来ました 🙌
ありがとうございます 🙏
