Issues with Function Returning Getters in Background Script of Chrome Extension

[rendomnet]

I'm developing a Chrome extension using Pinia for state management and have encountered a specific issue with getters in the background script. Getters that directly return values work as expected. However, getters designed to return a function, which then accesses part of the state, do not work correctly. Instead of returning the expected value, they return the function definition itself.

For example, this getter works fine:

getter1(state) {
  return state.someValue;
}

But this one does not, and just returns the function definition:

getter2(state) {
  return (key) => state.someValue[key];
}

In the above case, getter2 when called like store.getter2('key1') in the background script returns the function (key) => state.someValue[key] itself rather than evaluating it.

Could this be a serialization issue with how functions are handled in Chrome's background script environment, or is there a better pattern I should be using for such dynamic getters in Pinia within a Chrome extension background script?
