我在 node.js 服务器上使用 bitmovin-javascript。我正在尝试为我的 firebase 存储上的视频创建编码，并使用 bitmovin-javascript api 将输出保存在我的 bitmovin 帐户中。
我已经从用于 javascript 的旧 bitmovin api (v1) 升级（现在已弃用），我正在实施当前的 (v2)。但是每次我运行代码时，它都会显示HTTP 请求不成功：我的终端控制台中的 HTTP 响应代码是 403 Forbidden。
我已经交叉检查并确保我用来从 Firebase 存储中读取的 API 密钥（访问密钥和秘密密钥）是有效的，并且 bitmovin API 密钥也是有效的。用于 bitmovin 的输出 ID 也是有效的。
该 API 生成输入和视频编解码器配置、音频编解码器配置和清单，但不生成输出或编码。
该错误似乎发生在api试图创建编码资源的地方。
这是我的代码的样子：
const Bitmovin = require('bitmovin-javascript').default;
const start = async () => {
const bitmovin = Bitmovin({ 'apiKey': 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx' });
// create the input
const input = await bitmovin.encoding.inputs.gcs.create({

});
// create the output
const outputId = "XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX";
// create the video and audio codec configurations
const videoCodecConfig1 = await bitmovin.encoding.codecConfigurations.h264.create({

// create the encoding resource

我希望 api 能够读取我的 firebase 存储，对来自该存储的视频进行编码，将其存储在我的 bitmovin 输出下，为我提供指向输出的 bitmovin 链接，以便我可以将其保存到我自己的数据库中。
对此的帮助将不胜感激。
