Review and update the client-side code responsible for constructing URLs to ensure all dynamic variables are correctly defined and obtained before making API requests. Implement strict null or undefined checks and add logging to capture insufficiently resolved dynamic URI segments.

Enhance server-side validation by adding middleware that checks URL parameters for invalid states before processing. This should return detailed error messages to the client, suggesting corrections and reducing the likelihood of repeated malformatted requests.

Examine and revise configuration documentation and scripts to ensure all environment settings related to endpoint configuration are correctly set, particularly around resolving context IDs. This involves verifying that the service context identifiers are loaded into configurations accurately from secure sources.
