Context doesn't type null

[OmgImAlexis]

import KingWorld from 'kingworld';

type Data = {
    field: number;
}

const app = new KingWorld()
    .state<'result', Data | null>('result', null)
    .get('/', context => context.store.result.field)
    .listen(3000);
	 
console.log(`🦊 KINGWORLD is running at :${app.server.port}`);

Context is typed as the following.

(parameter) context: Context<TypedSchemaToRoute<MergeSchema<{}, {}>>, {
    result: Data;
}>

result should be typed as Data | null.

Currently if I run this I get the following error when browsing to http://localhost:3000.

null is not an object (evaluating 'context.store.result.field')

undefined also don't seem to be typed correctly, it just gets removed like null.

This seems to be the limitation of TypeScript, can you try set compilerOptions.strict to true and see if it now infers type correctly?

Here's a screenshot on my end, using strict: true results correct type.

However when using strict: false, null is missing.

Also you can use as instead of providing 2 generics to state, as it's intended for internal use.

Let me know if this work for you~
