Issue/Introduction

One of your users is unable to get report from Advance Reporting (Jaspersoft).

The user either receives the following error:

OR it looks like it is loading, but then stops and nothing happens

It works from Safari, but not Edge or Chrome.

 

Environment

Release : 15.9.3+

Component : CLARITY JASPERSOFT

Resolution

The Jaspersoft log indicated the root cause:
