Error message

Invalid environment variables\n\n${name}\n${issues.map((issue) => `  - ${issue.message}`).join('\n')}\n

What it means

Environment validation aggregator in the internal env module: after running each env variable through its declared standard-schema validator, any collected issues are formatted (variable name plus per-issue messages) and thrown as a stackless error at startup, so the app fails fast with a readable report instead of proceeding with invalid env configuration.
