How can i see the logs..

Also not able to decrypt in base64 manually..

Updated:
I found that logs store in S3 bucket have "Content-Type application/octet-stream". when i update content-type to "text/plain" .. is there any way set in bucket level content type or configure in kinesis data stream or firehose

enter image description here

Is there any way to set content-type kinesis stream or set the default content-type for s3 folder?

The data you posted appears to be compressed (I'd need a short file sample to be able to say that for certain). If I were you I'd look into compression settings for the log stream.

Here, it references some different compressions available for data: https://docs.aws.amazon.com/firehose/latest/dev/record-format-conversion.html

In a pinch, if you save those data in a file and give it the ".gz" extension, does the file become readable? (I'm not too hopeful since it says that the default compression scheme is Snappy and not GZIP, and I might be mistaken but I think I see a ZIP preamble after some kind of header in your screenshot).
