AWS LAMBDA 函数“无法读取未定义的属性‘s3’”

Question

I am using lambda AWS to convert mp4 to HLS and when I put my hostname: I am getting an error of the following:

{

"errorType": "TypeError",
  "errorMessage": "Cannot read property 's3' of undefined",
  "trace": [
    "TypeError: Cannot read property 's3' of undefined",
    "    at Runtime.exports.handler (/var/task/index.js:14:35)",
    "    at Runtime.handleOnce (/var/runtime/Runtime.js:66:25)"
  ]
}

Answer 1

It looks like the event your Lambda function is not a valid S3 event .

At a guess, you are manually triggering your Lambda function with a test event from the AWS console and you have supplied an non-conformant JSON structure.

Here is a minimal example of what you need in the test event:

{
  "Records": [
    {
      "s3": {
        "bucket": {
          "name": "my-s3-bucket"
        },
        "object": {
          "key": "HappyFace.jpg"
        }
      }
    }
  ]
}
