Oxidized won't run - Librenms configured as the device source

I’ve just installed oxidized on my LibreNMS server in order to integrate LibreNMS with oxidized. After the install, I modified the oxidized config to allow it to pull devices from LibreNMS. oxidized will not start, and crashes every time with the following error: “no implicit conversion of String into Integer”.

Here’s the crashfile output:

I have confirmed that my API key is working by issuing “curl -H ‘X-Auth-Token: MYAPIKEY’ http://127.0.0.1/api/v0/oxidized” and it returns JSON in the format below:
[
{
“hostname”: “fortigate1”,
“os”: “fortios”,
“ip”: “192.168.1.1”
},

Here is a copy of my oxidized config:

I’m at a loss here. Any reference I’ve been able to find of this issue so far was caused by a bad API key, but I’ve confirmed my API key is good, so i’m really striking out on a resolution.

Any help is greatly appreciated.
