Diff does not work on director/config/activity, because of problem with vars from Puppet

[linuxmail]

Expected Behavior

Check the diff on changes (which cames from Puppetdb import) should display the changed values

Current Behavior

After sync the I can't see the diff, but:

Oops, an error occurred!
Uncaught Error: Call to undefined function gipfl\Diff\PhpDiff\Renderer\Html\mb_strlen() in /usr/share/icingaweb2/modules/incubator/vendor/gipfl/diff/src/PhpDiff/Renderer/Html/ArrayRenderer.php:41

Possible Solution

It looks like, the parser has problems with vars.puppet...

• Rollback to a version, where it was working :-)

If I call it via facter, it looks for example:

root@mon-01: facter -p puppet_modules

apache, apt, apticron, auditd, augeas, base, certs, consul, cron, default, firewall, grub2, hosts, icinga2, icingaweb2, ntp, postfix, profile, python, resource_tree, rsyslog, settings, ssh, sudo, sysctl, systemd, telegraf, timezone, users

Steps to Reproduce (for bugs)

• Check out Master from Dirrector module
• Import from PuppetDB
• Have sync rules like

PuppetDB FC-R02 Hosts | ${facts.puppet_modules} | vars.puppet_modules |  
PuppetDB FC-R02 Hosts | ${facts.puppet_classes} | vars.puppet_classes |  

Your Environment

• OS: Debian Buster
• businessprocess | 2.3.1
• director | master
• incubator | 0.6.0
• ipl | v0.3.0
• monitoring | 2.9.3
• puppetdb | 1.0.0
• reactbundle | 0.7.0
• php 2:7.3+69

Guess you're missing the mbstring PHP extension, which is an installation requirement.

hi @Thomas-Gelf ,

pretty awesome .. it was really missing. Strange is ... I had this problem since a few days .. after one of the git pull from the module.

Anyway .. thanks :-)
