Node.JS Azure MySQL { [Error: Cannot enqueue Query after fatal error.] code: 'PROTOCOL_ENQUEUE_AFTER_FATAL_ERROR', fatal: false }

Question

I have app which connects to free Azure MySQL service and make queries in a loop. I use single connection to make those queries (I am limited to 4 connections), and process takes usually ~5 seconds. When I run app locally, it works perfectly fine, but after deployment do azure I get

{ [Error: Cannot enqueue Query after fatal error.] code: 'PROTOCOL_ENQUEUE_AFTER_FATAL_ERROR', fatal: false }

In my logs. How can I prevent this, and why does it work correctly locally, but not on Azure?
