Bundling flutterwave-node-v3 with rollup fails with a SyntaxError because the package used JavaScript reserved words like package as variable names. A maintainer confirmed the reserved-word usage was removed from the library. Bump flutterwave-node-v3 to the latest published version and re-run the bundler. The new package no longer declares variables named package, so commonjs bundling completes without the reserved-keyword error.
