• The default export from esbuild-copy-static-files may not be correctly imported as a namespace; switch to import copyStaticFiles from "esbuild-copy-static-files" or verify the module’s export shape to ensure the plugin loads properly.

import * as copyStaticFiles from "esbuild-copy-static-files";
