Nodejs Service crashed and exit after few hours [duplicate] - mysql

Question

I am trying to solve this issue for last 10 days. I tried everything I found on google.
I search and tried with many way but did not get any appropriate solution.
After running "npm start" at server at night I found this error at morning.
throw er; // Unhandled 'error' event
^

My Sql connection file:

I modified the mysql database with:
set global net_buffer_length=1000000;
set global max_allowed_packet=1000000000;
Everything I found on google I tried. but Failed at the end. So what to do now?

Answer 1

Updating "sequelize" and "mysql2" npm packages at Nodejs end with latest version solved the problem for now.
