I need help debug this problem. My app is in React, Node, Express and Postgres. I deployed it successfully on Heroku and the webpage showed static pages perfectly. But it went blank for the portion where it needs to fetch data from APIs. When I did Heroku logs, it gave me the error like below. Could anyone help me debug this problem?

PGSSLMODE to requireDB_USE_SSL to true
