Sequelize CLI [Node: 20.18.0, CLI: 6.6.2, ORM: 6.37.4]

I have multiple environments, and for lower environments I run the migrations using the config.json file. However, for Production I don't want to list the credentials in the file, nor do I want to have to set them up as env variables because there are multiple people working on the project and that means that all have to set them.

I would like to run migrations using the --url parameter

Using Postgres, stored on Neon.js. Running

npx sequelize-cli db:migrate --url "postgresql://{{username}}:{{password}}@{{host_url}}/{{db_name}}?sslmode=require"

is throwing an error

ERROR: connection is insecure (try using 'sslmode=require')

I tried using ssl=require, sslMode=require, sslmode=true, not providing it at all, etc.
However, I'm using this exact same connection string to connect the app to the DB, and it works fine. No matter what I do it doesn't seem to take the sslmode param into consideration. Any suggestions?
