Hi,

During a rebuild of all packages in sid, your package failed to build
on amd64.


Relevant part (hopefully):
> make[1]: Entering directory '/<<PKGBUILDDIR>>'
> NODE_ENV=release rollup --config build/rollup-config.js
> (node:1087360) Warning: To load an ES module, set "type": "module" in the package.json or use the .mjs extension.
> (Use `node --trace-warnings ...` to show where the warning was created)
> [!] RollupError: Node tried to load your configuration file as CommonJS even though it is likely an ES module. To resolve this, change the extension of your configuration to ".mjs", set "type": "module" in your package.json file or pass the "--bundleConfigAsCjs" flag.
