filter_by is causing a type error when checking for equality on a field with type string[]

filter_by is causing a type error when checking for equality on a field with type string[], despite providing valid results when run.

Example setup:

import { collection, setDefaultConfiguration } from "typesense-ts";

setDefaultConfiguration({
  apiKey: "xyz",
  nodes: [{ url: "http://localhost:8108" }],
});

const booksSchema = collection({
  name: "books",
  fields: [
    { name: "title", type: "string" },
    { name: "authors", type: "string[]" },
  ],
});

First example filter_by:

await booksSchema.search({
  q: "*",
  query_by: [],
  filter_by: "authors:=William",
});

Type error: Argument of type '{ q: string; query_by: never[]; filter_by: string; }' is not assignable to parameter of type '"[Error on filter_by]: Invalid token sequence: identifier with name `authors` followed by `:=`"'.ts(2345)

Second example filter_by:

await booksSchema.search({
  q: "*",
  query_by: [],
  filter_by: "authors:=[William]",
});

Type error: Argument of type '{ q: string; query_by: never[]; filter_by: string; }' is not assignable to parameter of type '"[Error on filter_by]: Unknown token: ["'.ts(2345)

Third example filter_by:

await booksSchema.search({
  q: "*",
  query_by: [],
  filter_by: "authors:=William Shakespeare",
});

Type error: Argument of type '{ q: string; query_by: never[]; filter_by: string; }' is not assignable to parameter of type '"[Error on filter_by]: Invalid token sequence: Literal Token `William` followed by literal token"'.ts(2345)
