Issues with pan: Why is firewall_cloud parser not parsing logs from Cortex Data Lake?

We are having issues with pan:firewall_cloud parser (which came with the Palo Alto Netowrks Add-on) not parsing logs from Cortex Data Lake. We are centralizing all of our SASE Prisma and Firewall logs into the Cortex Data Lake and then streaming them from there to Splunk Cloud via the HEC. When I configure that HEC to use the Source Type of pan:firewall_cloud, which was recommended in the setup docs,  we don't get field extraction. When I use a standard _json parser it extracts all fields as expected. Is anyone else having this issue? Is there a fix? I can't use any of the Palo dashboards and there is no CIM normalization happening without that official Add-on parser working.

Yes we did get the pan:firewall_cloud working. I am not sure why we were having issues at first, but we are good to go now.

We fixed this issue by changing the HEC endpoint that the data was being sent to from services/collector/raw to 
services/collector/event.

It's possible the app is out-of-date with Cortex Data Lake.  The app is supported by Palo Alto so you should contact them at https://splunk.paloaltonetworks.com/support.html
