Worked on the cloudflare/cloudflare-docs repository to deliver a targeted documentation update for KV-backed Durable Objects, focusing on clarifying the RangeError thrown when a value exceeds the 128 KiB limit. Used Markdown and technical writing skills to align the documentation with actual runtime behavior, ensuring that developers are accurately informed about the size constraints and error handling. Verified the behavior live to guarantee the documentation’s reliability and consistency with existing examples, such as SQLITE_FULL. This update improves developer guidance by reducing confusion during integration and helps prevent common mistakes when working with Cloudflare’s Durable Objects and KV storage limits.
