我收到了错误

   {
      "error": {
        "code": 400,
        "message": "Invalid value at 'audio.content' (TYPE_BYTES), Base64 decoding failed for \"ZkxhQwAAACAAA....\"",  

"status": "INVALID_ARGUMENT",

                "field": "audio.content",
                "description": "Invalid value at 'audio.content' (TYPE_BYTES), Base64 decoding failed for \"Zkxh...

当我执行request.sh bash 文件时，出现上述错误。

我该如何解决这个错误？或者有没有人和我一样有问题？

【解决方案1】：

看起来你也尝试过 Hakernoon 上 Sara Robinson 的代码。

我遇到了同样的问题，this post from ZodiacLeo123 帮助了我。

你必须添加“-w”标志

base64 -w 0 audio.flac

这会删除额外的新行。
