Knex: Timeout acquiring a connection when running `knex migrate`

I'm running ./node_modules/.bin/knex migrate:latest --env local

Which results in the following error:

> knex migrate:latest --env local

Requiring external module ts-node/register
Using environment: local
TimeoutError: Knex: Timeout acquiring a connection. The pool is probably full. Are you missing a .transacting(trx) call?

I've even tried deleting the database and re-running.

Are there connections I need to clear somehow? My app is not running.

Using the following

"knex": "0.19.0",

node -v: v14.0.0

psql (PostgreSQL) 11.7

Solution

  • Fixed this by simply downgrading to node version 13.11.0:

    sudo npm install -g n
sudo n 13.11.0
knex migrate:latest
#  Requiring external module ts-node/register
#  Using environment: local
#  Batch 1 run: 63 migrations

    Yay.
