Should the value type of the FieldSet interface include null?

[eugene-kim]

I thinknull should be included in the value of FieldSet given that null values are used to "empty" a field when modifying an Airtable record via the update or replace methods.

Or if FieldSet is intended to be the type of the values returned by the REST API, then perhaps another type should exist to represent value types passed into REST methods.

export interface FieldSet {
    [key: string]:
        | undefined
        | string
        | number
        | boolean
        | Collaborator
        | ReadonlyArray<Collaborator>
        | ReadonlyArray<string>
        | ReadonlyArray<Attachment>;
}
