Heroku - error KnexTimeoutError: Knex: Timeout acquiring a connection. The pool is probably full. Are you missing a .transacting(trx) call?

@mingxi as I linked above, you will probably need to tune your Knex pool (tarn) settings. All of those various issues I linked should have some additional context.

I can’t give you a copy paste answer for the tuning as it varies project to project.
