I believe when writting to MongoDB one cannot have empty strings but the default values of localhost bring something like:
{
"businessName" : "",
"businessWebsite" : "",
"city" : "",
"continent" : "",
"country" : "",
"countryCode" : "",
"ipName" : "",
"ipType" : "Residential",
"isp" : "",
"lat" : "",
"lon" : "",
"org" : "",
"query" : "127.0.0.1",
"region" : "",
"status" : "success"
}
Causing issues when testing the capabilities.
