@MosheEichler The links you listed are not correct.

• For Cortex XSOAR 6, you wrote https://docs-cortex.paloaltonetworks.com/r/Cortex-XSOAR/6.x/Cortex-XSOAR-Administrator-Guide/Automations
  But there is no URL for 6.x. You actually need to put a version there (6.12. or 6.13, etc.)
• For Cortex XSOAR 8 Cloud, the correct link is https://docs-cortex.paloaltonetworks.com/r/Cortex-XSOAR/8/Cortex-XSOAR-Cloud-Documentation/Scripts
  (In 8 Cloud, "automations" are known as "scripts".)
• For on-prem, the link is https://docs-cortex.paloaltonetworks.com/r/Cortex-XSOAR/8.x/Cortex-XSOAR-On-prem-Documentation/Scripts
  Again, you need to put in the actual version (8.5, 8.6, or 8.7)

All links need to be fixed according to this information.
