Error running "npm run helper:add"

Trying to add a helper, following the instructions from the readme. All is well until I run npm run helper:add, and I get the following error:

TypeError: Object.fromEntries is not a function

    at Function.Module.runMain (internal/modules/cjs/loader.js:774:12)

In the meantime, can I add a helper by just adding JSON directly to helpers.json?
