The following content pack versions of the Phishing and Malware packs caused Cortex XSOAR to possibly delete the corresponding incident types from the system. If they were deleted in the system, processing incidents of these types will fail.
Check if one or both of the incident types were deleted from the system.
If the Phishing and/or Malware incident types were deleted, you need to update these content packs to the latest version. Note that any customizations made to these incident types will not be retained and you will need to reapply all customizations to the incident types.
