node js for each dataset, connect database, perform select, update, insert query asynchronously

I am working on testcafe, in one of the data-driven test cases, for each test case, I am performing below set of database operations, connect, select, update, insert, close connection. The issue is when I execute forEach loop with only one dataset, it works well when I have multiple datasets, it fails with below error -

ConnectionError: Already connecting to database!
