oxidized: Getting Encoding::UndefinedConversionError at /node/version/view oxidized 0.20.0

Hi,

I’m getting the error mentioned at trying to view the configs in version view. My nodes are stored in a mysql db and I’m using git as output.

Here is my config:

interval: 3600
use_syslog: yes
debug: true
threads: 100
timeout: 200
retries: 3
prompt: !ruby/regexp /^([\w.@-]+[#>]\s?)$/
rest: 127.0.0.1:8888
next_adds_job: true
#vars: {}
#groups: {}
#models: {}
pid: "/home/oxidized/.config/oxidized/pid"

input:
  default: ssh, telnet
  debug: true
  ssh:
    secure: false

output:
  default: git
  git:
    user: Oxidized
    email: noc@localhost
    repo: "/srv/oxidized/repository/devices.git"

source:
  default: sql

  sql:

    adapter: mysql2
    database: oxidized
    user: oxidized
    password: xxxxxxxxxxxxxxx
    table: devices
    map:
      name: name
      ip: IP
      ssh_port: SSH_Port
      model: Device Type
      username: Username
      password: Password
      enable: enable
model_map:
  cisco: ios
  juniper: junos
  juniper: screenos
  fortigate: fortios
  checkpoint: gaiaos

Here is the trimmed output from journalctl
