"type": "module" with rollupTypes: true results in error

[christopherjbaker]

Describe the bug

If my package.json has "type": "module" and my dts plugin config has rollupTypes: true, I get the error Internal Error: getResolvedModule() could not resolve module name "./src/main".

I believe this is because module packages must use file extensions. If I comment out the line that removes .d.ts from the generated imports, it builds as expected.

I've solved updating the path of my tsconfig in dts into vite.config.ts

dts({
      include: ["./src/lib"],
      tsconfigPath: "./tsconfig.app.json",
    }),
