Worked on stabilizing UI routing for batch operations in the temporalio/ui repository, focusing on resolving navigation errors related to batch job ID handling. Addressed a bug where batch job IDs containing special characters were not properly URI-encoded, which previously led to routing failures and unreliable batch workflow navigation. Introduced a targeted fix by implementing the encodeURIForSvelte utility, ensuring that all batch job IDs are correctly represented in URLs throughout the application. Utilized TypeScript and front end development skills to deliver this solution, enhancing the reliability and consistency of batch operation navigation within the temporalio/ui codebase during the development period.
