# esmock-repro-cjs

Repro for https://github.com/iambumblehead/esmock/issues/218. Run `node test` to reproduce error.

## Issue

Mocking globally with the `import` key fails if a module has a CJS import:

```js

// src/test.js

import esmock from "esmock";

const logs = [];

await esmock("./index.js", import.meta.url, {}, {

	import: {

		console: { log: (...args) => logs.push(...args) },

	},

});

console.log("logs:", ...logs);

```

Error message:

```
