The error message lists 'azure-ad' as a supported method but the code also accepts 'azuread' as an alias. Consider updating the error message to include all accepted values: 'azure-ad/azuread, windows/ntlm, sql/sqlserver'.

Using the non-null assertion operator (!) on environment variables without validation could cause runtime errors if the required variables are not set. Consider adding validation to ensure SQL_USERNAME and SQL_PASSWORD are defined before using them.

There's an extra closing brace that creates invalid JSON syntax. This should be removed to maintain proper JSON structure.
