使用Google Docs API读取已存在文档时遭遇404错误的问题求助

我尝试用JavaScript的googleapis API读取Google Docs文件的内容，文件确实存在，请求也能正常发送，但读取内容时却收到了404错误。

复现步骤 #

• 创建Google Cloud项目（遵循官方创建流程）
• 在该项目中启用Google Docs API
• 创建一个拥有Owner角色的服务账号
• 编辑该服务账号，生成json格式的服务账号密钥
• 运行以下Node.js代码，会触发404错误：

const { google } = require("googleapis")

const auth = new google.auth.GoogleAuth({
    keyFile: "<path_to_service_account_key_json_file>",
    scopes: [
        "https://www.googleapis.com/auth/documents"
    ]
})

async function getDocumentContents(documentId) {
    try {
        const authClient = await auth.getClient()
        const docs = google.docs({ version: "v1", auth: authClient })
        const response = await docs.documents.get({ documentId })
        return response.data
    } catch (error) {
        console.error(error)
    }
}

(async () => {
    const documentId = "2PACX-1vRMx5YQlZNa3ra8dYYxmv-QIQ3YJe8tbI3kqcuC7lQiZm-CSEznKfN_HYNSpoXcZIV3Y_O3YoUB1ecq"
    const documentContents = await getDocumentContents(documentId)
    console.info(documentContents.body.content)
})()

我原本期望控制台能打印出目标文档的内容，但实际却收到了404错误。我到底哪里漏了？
