fields.value() data missing, despite setting values #14972
Description
Describe the bug
The issue happens when you assign form.fields to a variable and then attempt to access .value(). This:
const fields = test.fields; const initial = await input(); fields.set(initial);Results in:
// initial Initial: { "id": "019ab1c1-1b5e-770a-b6fc-de57e8fe44f3" } // fields.value() Values: {} Reproduction

serious, but I can work around it
Additional Information
The cause is that data?.input is empty undefined when accessed in the field proxy methods. Thus returning {} on .value().
data?.input undefined (get_cache(__)[''] ?? {}).input { id: '019a3697-fab9-7645-87ba-1902ec42a9df', name: 'Brooke Emberbreath', race: 'Human', class: 'Fighter / Arcane Trickster', campaign: 'Forgotten Realms', characterSheetUrl: 'https://www.dndbeyond.com/characters/154842629', imageUrl: 'https://i.imgur.com/ApkyJMQ.jpeg', firstLog: false }
