-`mysql2` is required for the `caching_sha2_password` auth method used by default in MySQL v8+. If you receive an `"ER_NOT_SUPPORTED_AUTH_MODE"` error when using the `mysql` driver, try adding the `mysql2` package to your project. You should then remove the deprecated `connectionString` parameter from your connection configuration in favor of the `username` and `password` values.
