rescript-schema 9.3.0: Cannot read properties of undefined (reading 'length')

[cknitt]

Using rescript-schema@9.3.0-rescript12.0:

@schema
type rule = {patterns: array<array<string>>}

@schema
type rules = array<rule>

@schema
type config = {rules: rules}

let _ = "{}"->S.parseJsonStringOrThrow(configSchema)

gives the following exception:

TypeError [Error]: Cannot read properties of undefined (reading 'length')

(instead of stating that the rules field is missing)

In sury@11.0.0-alpha.4, I get

SuryError: Failed parsing: Expected { rules: { patterns: string[][]; }[]; }, received { }

which is better, but I cannot use that version because of #124.

The #124 will be fixed in the next version, but I've dug quite a big hole with the change 😅 #152

Great, can't wait for v11 with the #124 fix. 👍
Maybe worth adding the above example to the test suite for v11.
