Hey! 👋 It looks like you’re trying to import an npm module without a build-step. Workers only natively support modules that are located in your upload directory, not node_modules. Check out https://miniflare.dev/recipes/esbuild.html for an example of using esbuild to bundle your code first. Let me know if you have any issues with this.
