Examples

Error.BadRequest("Request body is not valid JSON")
Error.BadRequest("Missing required header: Authorization")
Error.BadRequest("Invalid date format in query parameter")

Remarks

Use BadRequestError for syntactic errors (malformed JSON, missing required fields, invalid format). For business rule violations, use ValidationError or DomainError instead.

This represents a client error that should not be retried without modification.
