Worked on the OpenTripPlanner repository to enhance the Transmodel API by introducing greater flexibility in handling duration values for the Cost scalar. Leveraging Java and GraphQL, implemented support for integer durations alongside existing string values, addressing type-related errors and improving compatibility for client integrations. Addressed a parsing issue in the CostScalarFactory to prevent NullPointerExceptions when processing integer durations, thereby increasing runtime reliability. Updated documentation written in Markdown to clarify guidance on configuring unbounded transit service periods, making long-duration scenarios easier to manage. The work focused on backend development, configuration management, and clear documentation to streamline integration and usage.
