GA4 Key event metric not showing on Looker Studio

Hello, my looker studio dashboard is using GA4 as data source. I created a key event on GA4 weeks ago, it was recording data perfectly fine. However when I tried to import this into my dashboard, it always shows "Data Set Configuration Error". 

Key event are perfectly fine on GA4
