targetUserId type doesn't allow null

js-api-client/src/index.d.ts

Lines 650 to 668 in 3559932

	* @param targetUserId - ID of the user who will see the recommendations.
	* Specifying the *targetUserId* is beneficial because:
	* * It makes the recommendations personalized
	* * Allows the calculation of Actions and Conversions
	* in the graphical user interface,
	* as Recombee can pair the user who got recommendations
	* and who afterward viewed/purchased an item.
	* If you insist on not specifying the user, pass `null`
	* (`None`, `nil`, `NULL` etc., depending on the language) to *targetUserId*.
	* Do not create some special dummy user for getting recommendations,
	* as it could mislead the recommendation models,
	* and result in wrong recommendations.
	* For anonymous/unregistered users, it is possible to use, for example, their session ID.
	* @param count - Number of items to be recommended (N for the top-N recommendation).
	* @param optional - Optional parameters given as an object.

	constructor(
	itemId: string,
	targetUserId: string,

The docs align with the API docs on your site's API reference, and mention passing null, however the type only allows string. Based on the docs, it seems like string | null should be the type. I'm casting in my own code.

Note

I only referenced on occurrence, but this is a repeated issue.
