Rollup packaging error, how to handle it

I tried using a third-party package, but there is a TS file in it, which caused me to have a problem with the packaging. I don't know how to handle it

Why would it introduce nodes by default_ The ts file in modules

It would be great if you could provide a minimal reproduction.
