[ixpmanager] Error message creating mrtg config file

[Barry O'Donovan (INEX)]

Hi Jose,

from what I can see via:

[2021-07-22 18:01:03] production.ERROR: Argument 1 passed to 
IXP\Services\Grapher\Renderer\Extensions\Grapher::escapeCommunityForMrtg() 
must be of the type string, null given

it looks like your switch has no SNMP community set?
