Frequently Asked Question

Symptom

• When printing a Webi report in PDF/XLS format, some N4V components are not correctly printed (a puzzle may appear) or there is a very long delay to print the report.
• This error only appears in Linux N4V deployment

Environment

• Linux Server
• Need4Viz : all versions

Resolution

To install the N4V solution on a Linux server, a proxy configuration has been used (to get from internet the modules used by N4V).

After the installation, the proxy configuration must be deleted to enable the correct printing of N4V components.

To fix the issue, follow the steps :

1. Delete the environment variables http_proxy et https_proxy from the .bashrc profile
2. Source again the .bashrc profile to be sure the variables are not loaded in the profile
3. Test a CURL command to be sure the proxy is not set (CURL should give an error)
4. run "pm2 stop all" to stop all the N4V services
5. run "pm2 kill" to stop the pm2 deamon
6. run "pm2 start apps_ce.json" to launch again the pm2 daemon (and run the N4V services)
7. Print again your Webi report included N4V components
