RollupError: Entry module "./src/node/index.ts" cannot be external.

Since latest update 5.1.0 -> 5.1.1, I have this error when building

./src/node/index.ts → ./dist/esm, ./dist/cjs...
[!] RollupError: Entry module "./src/node/index.ts" cannot be external.

My config

  {
    input: "./src/node/index.ts",
    output: [{
      dir: "./dist/esm",
      format: "esm",
      exports: "named",
      preserveModules: true,
      sourcemap: true,
      entryFileNames: "[name].mjs",
    }, {
      dir: "./dist/cjs",
      format: "cjs",
      exports: "named",
      preserveModules: true,
      sourcemap: true,
      entryFileNames: "[name].cjs",
    }],
    plugins: [externals(), ts()]
  },

Maybe it's related to the patch Consider an empty include option means 'includes all'.

You're absolutely right. I should have written some test for this case.

Thanks for reporting. This is fixed in the upcoming 5.1.2.
