I can't connect planetscale securely.

[artemismars]

Using tools

1. MySQL2
2. Sequelize
3. Express
4. Heroku

I sent post request to server api from postman.
But it says this error.

I went to .env file and changed DATABASE_URL value. Like ?ssl={}
But it didn't work.
How to solve this issue?

My app is deployed on heroku now.
