TavilySearch construct args act incorrectly when invoked

Checked other resources

[x] I added a very descriptive title to this issue.
[x] I searched the LangChain.js documentation with the integrated search.
[x] I used the GitHub search to find a similar question and didn't find it.
[x] I am sure that this is a bug in LangChain.js rather than my code.
[x] The bug is not resolved by updating to the latest stable version of LangChain (or the specific integration package).

Example Code

const tool = new TavilySearch({
  maxResults: 3,
  includeAnswer: true,
});
console.log(tool.includeAnswer);//true

(async () => {
  const res = await tool.invoke({
    query: search,
  });
  console.log("result:", res.answer);//❌null
})();

Error Message and Stack Trace (if applicable)

No response

Description

The parameters I entered during construction did not work，not only the includeAnswer, the maxResults is also default(5) when response back but i set it 3
