Products

Issue/Introduction

Intermittently, on the Unified main server console > custom rule page, click on details to view custom rules from other instance, getting error "Something went wrong! See the error log for more details."

Environment

• App control Unified Management:8.1.8, 8.1.10

Cause

This is a known bug EP-11734 which will be fixed on a future version.
