Can not connect to Postgres instance

[Nhat Khanh Le Dinh]

My Postgres instance and deploy nodejs app are on the same project, I tried this connection string: pg://postgres:[Password]@/[DB]?host=/[Instance_name] but Knex always return this error: Knex: Timeout acquiring a connection. The pool is probably full. Are you missing a .transacting(trx) call? How to fix this, thank you.
I tried this on my local machine (Allow my IP) and it works fine.

Could you try this example. If you get the same error, elaborate how are you connecting to the instance.

Hi Nhat,

I'm having exactly the same issue. The response below was not helpful (neither the example nor the connecting link) but I suspect there is an issue with how we are writing the connection string. Were you ever able to solve your problem, and if so, how?

Hi Justin, 

Are you using App Engine Standard? I don't believe that the Node.js runtime supports connections with PostgreSQL on CloudSQL at this time.

Thanks,
