Fix InvalidInputError
in TypeScript
✅ Solution
InvalidInputError usually indicates that the provided input fails to meet the expected type or format, especially within conditional branches or exhaustiveness checks. Resolve this by carefully validating input types, ensuring all possible input values are handled in conditional statements (e.g., using `else` or a `default` case in switch statements), or employing type guards to narrow down input types before use. Alternatively, if using discriminated unions, verify that exhaustiveness checks cover all union members by using `never` or a similar mechanism.
