When idFrom is 'ARGS', and no args present, throws error

[crcatala]

When idFrom is set to 'ARGS', api methods that don't require arguments ends up throwing errors.

For example:

getList.operation = 'READ';
getList.idFrom = 'ARGS';
function getList() {
  const url = `${BASE_URL}search?query=react&hitsPerPage=200`;
  return fetch(url)
    .then(response => response.json())
    .then(result => result.hits);
}

api.hackernews.getList().then(hits => this.list = hits);

Calling getList() throws:

Error: Value is missing id, tried to add to entity products

Interestingly, passing any arg (even though not used by the api method) will make the call work as intended. i.e api.hackernews.getList('hello').then(hits => this.list = hits)
