Decode the final `output.json` from the `LocalTestingTool` #22

Hi,

I have managed to get the full flow running to aggregate debug reports in the browser and process them locally with the provided tool.

The final file output I have is:

[{"bucket": "d0ZHnRzgTJMAAAAAAAAAAA==", "metric": 195000}]

Which looks correct in terms of there should be a single key and the metric value is correct.

The issue I have is now decoding this bucket to get my original input data, I assumed the steps would be:

But this causes the following error:

_cbor2.CBORDecodeEOF: premature end of stream (expected to read 23 bytes, got 15 instead)

Would really appreciate any help on how to get the input data back out of this bucket.

Best, D

Hi Dennis,

Please do a base64 decode on the bucket and you should be able to get your key.

Thanks!
