Handling Optional Fields in JSON Schema with `S.UndefinedOr` and `S.OptionFromUndefinedOr`

New Schema -> JSON Schema issue

So in our codebase, we take advantage of

JSON.parse/stringify

JSON.parse/stringify

's behavior around

undefined

undefined

and define all optional fields in our models as

S.UndefinedOr

S.UndefinedOr

S.OptionFromUndefinedOr

S.OptionFromUndefinedOr

instead of using

S.optional

S.optional

. This makes all our code more explicit, among other benefits.

However, I haven't been able to figure out how to get

S.UndefinedOr

S.UndefinedOr

and

S.OptionFromUndefinedOr

S.OptionFromUndefinedOr

to behave the same as

S.optional

S.optional

when using

JSONSchema.make

JSONSchema.make
