Cannot save policy changes successfully after updating combined object rule via Web VPM

• ProxySG Software - SGOS

Issue/Introduction

Customer currently has proxy servers in PRODUCTION running 7.3.18.3 (Web VPM 2.2.10) and want to upgrade these to SGOS 7.4.12.3.

The upgrade started in DEV and was successful - with the Management Center referencing the upgraded Edge SWG server running 7.4.12.3.

However, when the Edge SWG admin tried changing the logical name of a rule within the policy, attempting to Save the policy in management centre causes the session to hang as shown below - only way to get back to the setup is to close the tab and start a new one again to the Management Center.

Making the same change from the individual Proxy VPM directly also shows the same issue - so the problem lies with the VPM.

Digging into the rule in more details, it was identified that a combination needed to exist for this 'hang' to happen i.e. problem appears to be related to nested rules; having an individual rule within the same web access layer allowed the Edge SWG admin change and save the rule name without any issue.

Environment

Combined rules within Policy.

Cause
