Issue with Type Inference in Schema Transformation

export const CreateDialingPermissionsSchema = Schema.Struct({
    ...ClientSchema.fields,
    updateRequest: Schema.transform(
        Schema.String,
        Schema.Array(DialingPermissionEntrySchema),
        {
            decode: (input) => JSON.parse(input),
            encode: (input) => JSON.stringify(input),
        },
    ),
});

export type CreateDialingPermissions =
    typeof CreateDialingPermissionsSchema.Type;

updateRequest: Schema.transform<typeof Schema.String, Schema.Array$<Schema.Struct<{
        iso_code: typeof Schema.String;
        low_risk_numbers_enabled: typeof Schema.Boolean;
        high_risk_special_numbers_enabled: typeof Schema.Boolean;
        high_risk_tollfraud_numbers_enabled: typeof Schema.Boolean;
    }>>>;
    accountSid: typeof Schema.NonEmptyString;
    authToken: typeof Schema.NonEmptyString;
