Hello,
Try this:
Correlate “Q4EkA5HnP8gKtHtcWjEhmg--HRC9EseoUCtD1XwHpSSkcw--” and “XwF2well-bMrkfhcyVLtAA== “(both are highlighted in below print screen) which are sap-ext-sid and sap-wd-secure-id and your script will run without any issue.
You can use below link to Decode custom request’s body and use correlation finder to excel utilities to find in which request correlation value is comeing,
Let me know if you face any other issue.
Thanks,
Deepak
