`TypeaheadField` constructor `description` parameter is required, should be optional (TS2345)

[paperboyo]

Hi. Sorry, my helpful robot insists it found something. I obviously don't have a clue. Please excuse me and close if it's shrooms...

Severity: Medium — forces callers to pass dummy values.

Error:

Argument of type 'undefined' is not assignable to parameter of type 'string'.

at new TypeaheadField(id, name, undefined, resolver, "TEXT") — the third argument (description) is typed as string but many callers don't have a description.

Current declaration:

constructor(
  id: string,
  name: string,
  description: string,            // ← required
  resolver?: TypeaheadResolver | undefined,
  suggestionType?: SuggestionType
);

Proposed fix:
Make description optional with a default:

constructor(
  id: string,
  name: string,
  description?: string,           // ← optional
  resolver?: TypeaheadResolver | undefined,
  suggestionType?: SuggestionType
);

or, if changing the positional API is undesirable, accept string | undefined:

constructor(
  id: string,
  name: string,
  description: string | undefined,
  resolver?: TypeaheadResolver | undefined,
  suggestionType?: SuggestionType
);

and default to "" in the body:

this.description = description ?? "";
