"module.export =" - prefix is not prepended correctly to sourcemap

[PatrickDahlin]

Since working with sourcemaps I've found that the sourcemap needs to be uploaded with the module.export prefix to work.
This looks like it's handled in "generateSourceMaps", however, while debugging I've found that it's never ran, nor affects the output.

Tl:dr; It looks like the toString wrapper doesnt work anymore.

module.exports = should be added when renaming the file.

Solution before fixing:

/**@type {() => import("rollup").Plugin} */
function sourcemapToJs() {
  return {
    writeBundle(options) {
      if (options.sourcemap && options.file) {
        const str = fs.readFileSync(`${options.file}.map`, {
          encoding: "utf-8",
        });
        fs.writeFileSync(`${options.file}.map`, `module.exports = ${str}`);
      }
    },
  };
}

And add it to rollup:

export default defineConfig({
  plugins: [
    /** other plugin */
    sourcemapToJs(),
    screeps(),
  ],
});
