Env: wp-env pipelines are failing with a MySQL connectivity error

[lephleg]

Description

Well, I don't know if this is the most proper place to report this, but:

There's something wrong with the wp-env tool which automatically configures the development environment of WordPress and Gutenberg. I receive a MySQL connectivity error in my local installation with a false username (username_here). I can also see the same error all over the place in the PRs submitted recently (the last 22 hours) and got through the automated tests pipelines.

Step-by-step reproduction instructions

1. Follow the Getting Started Contributor's guide
2. Execute the npm run wp-env start command

Expected behaviour

Docker containers to start successfully.

Actual behaviour

Receive an error like the following:

✖ Error while running docker-compose command.
mysqlcheck: Got error: 1045: Access denied for user 'username_here'@'172.31.0.5' (using password: YES) when trying to connect
