im trying to import fs and keep getting the error in the title. Im pretty sure im importing it from the server side. this is the file im importing it from. its in the root of my project (not app directory).

import fs from "fs"
import openai from "./OpenaiClient"

if (!openai) {
throw new Error("OPENAI_API_KEY is required")
}

export async function getAssistant() {
const file = await openai.files.create({
file: fs.createReadStream("../bls/BLS_Test.json"),
purpose: "assistants",
})
random code ......
}
