Block type optional properties.

[MarcelKlammer]

the block types

BlockShelley
BlockAllegra
BlockMary
BlockAlonzo
BlockBabbage

in

@cardano-ogmios/schema

have the ? (optional) modifier set for their properties:

body?
headerHash?
header?

See here:

ogmios/clients/TypeScript/packages/schema/src/index.ts

Line 1349 in d4d27a7

export interface BlockAlonzo {

This ? (optional) modifier should be removed, as those properties of a block are actually not optional.

Ho! Good catch. The JSON specification (which is the source from which the TypeScript type definitions are generated) is missing a required field to make those properties non-optional.
