The output was on bytes, while I wanted this to be the text/string; should look something like this,

  • hi @JasonRStevensCFA - ended-up with another error.. – SivaKumar AWS Jan 13 '20 at 01:02
  • My apologies but I am likely beyond my bounds of helpfulness here. If you haven't already I'd look into your original string encoding (do you need to decompress first? `zlib` is nice, if so). Other than that, sorry! – Jason R Stevens CFA Jan 13 '20 at 22:00
  • Thanks @JasonRStevensCFA - I was able to inflate the zipped base64 string using zlib. json_str = zlib.decompress(base64.b64decode(data), 16 + zlib.MAX_WBITS).decode('utf-8') Reference thread, https://stackoverflow.com/questions/37022199/python-how-to-inflate-gzipped-base64d-string – SivaKumar AWS Jan 16 '20 at 23:50
