}

If you're using queries, you need to use listDocuments() instead. getDocument() can only be used if you are fetching a single document that you have the ID of already

I want to check whether userId with postId is present in the collection or not. Thats why I am using Query.and()

So you want to get a list of documents that have a specific userId and postId?

It will only be a single entry, not multiple

That shouldn't matter, it'll just return the one entry if there is only one. If you are doing anything with queries or you do not already know the ID of the document, you will need to use listDocuments() to fetch the data

after using listDocuments() its giving Argument of type 'string' is not assignable to parameter of type 'string[]'. forquery

Wrap your query variable in an array, like this
const likes = await db.listDocuments(palettegramDB, likesCollection, [query]);

ok
