Worked on the grammyjs/website repository to improve documentation accuracy and deployment security for Vercel Edge Functions. Addressed a critical bug by updating the webhookCallback adapter references in Markdown documentation to use HTTPS, ensuring that deployment instructions matched actual runtime requirements and reducing the risk of misconfiguration. The technical approach involved careful review and correction of example code and explanatory text, aligning documentation with the secure practices needed for Vercel environments. Focused exclusively on documentation, the work emphasized clarity and correctness, leveraging Markdown to communicate configuration details and prevent potential integration issues for developers deploying with Vercel Edge Functions.
