Webhook log: FS Webhook processor init failed

Edgar_EduardoZukermann_Cortes — Mon, 17 Apr 2023 18:00:54 GMT

Hello,

I am seeing hundreds of SEVERE and WARNING level log errors pertaining to webhooks, yet I have no webhooks set up yet against any of the hosted feature layers:

WARNING Webhook log: FS Webhook processor init failed Connecting to queue : FS_Raw_Events_Queue failed.

SEVERE Webhook log: init WebhookProcessors failed. FS Webhook processor init failed.

Has anyone else seen this?

Recently applied ArcGIS Server 11.0 Directory Traversal Vulnerability Patch, however the problem persist.

Did you open the ports for the Data store? "25672 and 44369 (TCP)—These ports must be available (free) on the relational data store machines if organization members will create service webhooks (a beta feature at this release) in the ArcGIS Enterprise deployment. 45671 and 45672 (TCP)—To use webhooks, you must open these ports on the relational data store machines to allow communication with the ArcGIS GIS Server where the feature services configured to use webhooks are running." https://enterprise.arcgis.com/en/data-store/latest/install/windows/ports-used-by-arcgis-data-store.htm

Hello - I posted on this topic late last year:

https://community.esri.com/t5/arcgis-enterprise-questions/arcgis-server-11-0-directory-traversal/td-p/1219790

I was able to resolve the issue by re-starting the data store service after applying the traverse patch. But it is interesting that you are seeing the errors before applying the patch. I did not see these webhook errors until after applying the patch.

There is a documented Esri bug on this topic:

We just upgraded to Enterprise 12.0 and we are seeing this Bug. Will the same fix work at 12.0?
