There may be an issue where users experience an issue when attempting to access an exception on the ARC screen resulting in getting the following error:
Here are the following instructions to resolve this issue:
- Stop the Collector
Usually
sudo systemctl stop takipi
from the collector machine
Make sure process is actually down by runningps -ef | grep takipi-service
- Wipe Collector data
From the Collector machine, go to Collector home dir (/opt/takipi e.g.)
Run./etc/takipi-wipe-data
(it may need a sudo)
Make sure we get “Successfully wiped collector’s data!”
- Stop the Backend
Go to server home (/opt/takipi-server e.g.)
Run./bin/takipi-server.sh stop
Make sure process is acutually down by runningps -ef | grep java
- Remove Backend cache directory
Go to server home (/opt/takipi-server e.g.)
Runrm -rf temp/*
- Change Backend classes nonce
Go to server home (/opt/takipi-server e.g.)
Edit my.server.properties by runningvi conf/tomcat/shared/my.server.properties
Append the below lines to the file
JAR_BYTECODE_NONCE=JBN_VISA_NEWJAR_ANALYSIS_NONCE=JAN_VISA_NEW
- Start the Backend
- Start the Collector
- Wait for new events, then try to open them.
Events should start to come in and users will now be able to access their data from the ARC screen.
