Explicitly set undefined column value to null

[triozer]

Description

This pull request ensures that when a field does not have a defined value it's set to null. Allowing to clear it.

Testing

• Set values to null when re-syncing a spreadsheet
  • Import a spreadsheet
  • Remove any value (not the slug)
  • Re-sync the spreadsheet
  • Check that the field value is either unset or set to the default value (in case of a number)

This won't work right - because we don't accept null at the moment for anything other than collection references.

This got merged, so this works now 🕺🏽

If you try and import this sheet, it will fail: https://docs.google.com/spreadsheets/d/1TcedbEOK3L9a4BCArLRkjHa5hgXtBZ93dzAL54eGApM/edit?gid=0#gid=0

Wait why are we not just omitting these values? It's not required that you pass values for all fields.

[triozer]

Doing so would keep the previously set value

[tom-james-watson]

That feels like we made a bad design decision there 🤔

[triozer]

So yeah, this won't unset the value but just keep it as is

const managedCollection = await framer.getActiveManagedCollection()

await managedCollection.addItems([
  {
    id: "test",
    slug: "test",
    fieldData: {
      "First Name": {
         type: "string",
         value: "John",
      },
    },
  },
])

await managedCollection.addItems([{ id: "test", slug: "test", fieldData: {} }])
