Setup

Issue: mikro-orm/mikro-orm#4216

This reproduction was run on Node 18.15.0 with PNPM 8.2.0

To install Node 18.15.0, you can use nvm (https://github.com/nvm-sh/nvm), nvm install 18.15.0 + nvm use 18.15.0. To install pnpm, run npm install --global pnpm.

The test script in package.json creates a Docker container running Postgres 13.2, migrates some table definitions into it, then invokes the run.ts file. Once it completes, it tears the Docker container down.

Broken version

To reproduce:

• pnpm install
• pnpm test

This should throw an error when the code is finished running:

Working version

To show that it works on 5.6.15:

• Replace ^5.6.16 in package.json with 5.6.15 (no caret ^)
• rm -rf node_modules/ pnpm-lock.yaml
• pnpm install
• pnpm test

This should print out the line: Found the order: 1234
