Worked on the thingsboard/swagger-ui repository to enhance numeric parameter range validation within the utils module. Focused on refining the validation logic to enforce inclusive minimum and maximum checks, ensuring that values at the boundaries are correctly accepted. Improved error messaging to provide clearer feedback when range violations occur, making it easier for users to understand validation failures. Updated and expanded unit tests to reflect the new inclusive behavior and messaging, supporting ongoing maintainability. Utilized JavaScript for backend development and testing, aligning changes with existing validation patterns to promote consistency and code quality throughout the repository during the development period.
