Synthetics: Get S3 bucket/key location at runtime

Question

Is there a way in a CloudWatch Synthetics script (nodejs) to get the S3 bucket and key location for artifacts during runtime? I see log messages like:
```
S3 destination for uploading artifacts determined: 
{
    "s3Bucket": "cw-syn-results-accountid-region",
    "s3Key": "canary/region/name-uuid/2021/12/28/time"
}
```
Can I get that bucket and key for use in my script, even if it's unofficial and may break in future canary versions?

Answer

There is no currently supported way to do that.

If you need that information, this currently works (testing using `syn-nodejs-puppeteer-3.3`):

```
const uploader = require('SyntheticsUploader');

await uploader.setUpUploader();
const s3Path = 's3://' + uploader.getS3Path();
```

It is completely unsupported, though.
