Fix .env file syntax
.env files use KEY=VALUE format. Invalid syntax—spaces around =, unquoted values with special chars, or wrong line endings—can cause parse errors.
Common causes
- Spaces around = in KEY = VALUE.
- Unquoted value containing # or spaces.
- Windows line endings (CRLF) in some parsers.
How to fix
- Use KEY=VALUE with no spaces, or quote values containing spaces.
- Quote values with #, =, or spaces.
- Validate with Env File Validator.
