Facing ERROR Akamai SIEM Integration App 1.4.4

[kishor_pinjark2]

I installed the App - Akamai SIEM Integration (https://splunkbase.splunk.com/app/4310/)

Steps for integration - https://learn.akamai.com/en-us/webhelp/siem/siem-integration/GUID-723D1E95-922D-4A87-ABD9-21135BD742...

After creating new data input, I am seeing error messages in splunkd and no data ingestion.

01-09-2019 04:28:00.448 -0600 ERROR ExecProcessor - message from "/opt/splunk/etc/apps/TA-Akamai_SIEM/linux_x86_64/bin/TA-Akamai_SIEM.sh" com.akamai.siem.Main.streamEvents(Main.java:1023)\com.splunk.modularinput.Script.run(Script.java:74)\com.splunk.modularinput.Script.run(Script.java:48)\com.akamai.siem.Main.main(Main.java:321)\
