The search in the tutorial map is not not working

Like i said in the title its not working AT ALL. I think in the past it used to work maybe around 5-6 months ago but now it doesn't work at all like i can't name of the lesson and that show tasks button is also not working.
I hope you this fix this issue soon. Have a nice day😁.

首先，重現 issue 中描述的教學地圖搜尋失敗問題，以及無法運作的「Show tasks」按鈕。追蹤教學地圖的進入點，並確定課程和工作篩選的預期行為；完成的標準是兩個控制項都恢復運作，且相關互動已獲得驗證。
