ERR_MODULE_NOT_FOUND when imported in an mjs file

In my `mjs` file:

```
import {printf} from "fast-printf";
```

Error thrown in console:

`Error [ERR_MODULE_NOT_FOUND]: Cannot find module '/xxx/node_modules/.pnpm/fast-printf@1.6.3/node_modules/fast-printf/dist/esm/src/createPrintf' imported from /xxx/node_modules/.pnpm/fast-printf@1.6.3/node_modules/fast-printf/dist/esm/src/printf.js`

(replaced full path prefix with `xxx` for readability).

Is this related to the library, or am I using node in a wrong way? Please advise.
