Error: EISDIR: illegal operation on a directory, read

Hi, I repeated the steps shown in this article https://www.skovhus.dev/blog/flow-to-typescript-migration
Unfortunately, this is what I get.

npx @khanacademy/flow-to-ts --write  --delete-source src
internal/fs/utils.js:307
    throw err;
    ^

Error: EISDIR: illegal operation on a directory, read

}

Thanks for help.
