Fixes https://github.com/akaday/react/security/code-scanning/21
To fix the problem, we need to ensure that the
req.query.nameparameter is a string before using it. If it is not a string, we should handle it appropriately, such as by returning an error response. This can be done by adding a type check forreq.query.nameand ensuring it is a string before proceeding with the rest of the code.Suggested fixes powered by Copilot Autofix.
