Description
Description
Lodash uses Function(String) which is unsupported in the v8 Edge runtimes like Cloudflare Workers. This is being picked up by transpilers, like the one in Next.js which prevents projects being built and deployed on platforms like Vercel.
Example error messages in Next.js projects
