I was facing a similar problem and using the mysql2 module helped me.

$ npm install mysql2 --save
$ npm uninstall mysql --save

This issue was caused by node.js version. With node.js 10.19.0 my app work, but with node.js v 12.x.x - not.

For me, it is An Error that the entity directory is fasle.

     entities: [__dirname + '/**/entity/*.entity{.ts,.js}'],

Change the directory and You can see it works.

You can also try --tls-min-v1.0 when running node

nodejs/node#27384

node --tls-min-v1.0 app.js

this worked for me (node 14.15.1),
