Strapi Deployment

Hi everyone.

I would like to know if anyone is having problems with the Knex module when they do some kind of deployment.

I’m trying to deploy in Render and I’ve been with this error for days:

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

I am using Strapi v.4 and the error started when I made a new deploy in which I had only modified some models of the database.
So far, the only thing I have found has been this thread:

Basically it is to change the versions of JSON packages and if you do, you get something similar to a Strapi version 3.

It seems that there may be some version compatibility issues with knex/pg/node.
Any suggestion? Thanks
