**What**
Changes the order of object type evaluation to properly handle null properties.
Previously, `stringifyNullProperties({ test: null })` would fail in the 2nd iteration due to an attempt to iterate `null` in `Object.keys(obj)`.
**What**
- convert fulfillment service to typescript
I have removed the `transform` parameter from the getFulfillmentItems_ function since it was not being used with different methods, only `validateFulfillmentLineItem_`. Instead I have just reference the validateFulfillmentLineItem_ function directly.
We have the same pattern across some different methods, is there a specific reason or just for future proofing?
### What
At the moment it is not possible to pass explicitly null on a property since the qs.stringify will transform it as `url?property=` which is then interpreted on the backend side as `""` value which is not what we expect.
The actual way to pass null value is to set the property as `{ prop: "null" }` in order to get the stringify method to send it correctly.
### How
I just created a small util that loop through the input object and transform all null values to "null" before being passed to the qs.stringify method.
The new util is only applied on the list batch job since this is for now the only place that require that behaviour.
### What
At the moment, it is not possible to not invalidate any queries>
Example, when we want to Create a new signed url, it does not require to invalidate any of the queries.
But the way it is done in the buildOptions, require to give either a key or an array of keys.
### How
The behaviour for empty array is to invalidate all the queries and here we would like to be able to just pass undefined in order to not trigger the invalidation. The update allow the arg to be optional and check for undefined explicitly before choosing the invalidation
