info: Deno supports CommonJS modules in .cjs files, or when there's a package.json
with "type": "commonjs" option and --unstable-detect-cjs flag is used.
hint: Rewrite this module to ESM,
or change the file extension to .cjs,
or add package.json next to the file with "type": "commonjs" option
and pass --unstable-detect-cjs flag.
