undefined currentUser in redux thunk

Here is the cloned repo I'm working in: https://github.com/mkrul/web-template (yes I'm aware this is using some VERY outdated conventions. I have plans to refactor this but right now I'm just trying to get things working as expected)

I've succeeded in creating a redux thunk that updates the currentUser's deliveryAddress, however, this change only populates in state after a hard refresh of the page.

https://github.com/mkrul/web-template/blob/main/src/containers/SearchPage/SearchPage.duck.js

Code in question:

export const setDeliveryAddress = address => (dispatch, getState, sdk) => {  dispatch(setDeliveryAddressRequest(address));  // Make API call to update the user's delivery address  return sdk.currentUser    .updateProfile(      {        publicData: {          deliveryAddress: address,        },      },      { expand: true }    )    .then(() => {      dispatch(setDeliveryAddressSuccess());    })    .catch(e => {      dispatch(setDeliveryAddressError(storableError(e)));    });};

In the redux dev tools, I see the action to SET_DELIVERY_ADDRESS_REQUEST followed by SET_DELIVERY_ADDRESS_ERROR. The error response reads that state.currentUser is undefined. I notice the pattern of returning sdk.currentUser from elsewhere in this codebase, so I'm not sure why currentUser wouldn't be initialized here.

The interesting thing is when I hard refresh the page, I do see changes to the deliveryAddress populate in state. So it's working, but just not immediately as expected.
