Exact field input mongoose for nodejs - regex

Question

I've recently been attempting to pull my hair out getting stuck on what I would call a trivial issue.
The way mongoose in nodejs handles the specific field inputs. I have a specific issue where mongoose is not doing the same as mongodb is doing.
The issue is the following, if I use a "-" symbol in my field name, mongoose seems to run some weird operation on it, instead of accepting it as part of a string.
I've tried running several regex commands, some / escapes, however it should literally just take the input, as I know the specific data I'm looking for.
The code causing the issue is the following:
datapoints.find({type: "charging-type", device: device._id})
.exec(function(err, objects){
if(!objects){
log("Can't find objects");
}
});
Going straight into mongo shell and typing:
db.datapoints.count({type: "charging-type", device: device._id})
taking out the type makes everything work, changing the type to for example: shuntvoltage, current, ... all work perfectly.
The problem thus occurs with the usage of this - symbol.
What would be the way to enter this inputstring with a special character as an exact string?
Any help would be much appreciated.
Edit as per request; I don't get any error, I get objects==undefined (or !objects), schema is below.
var datapointSchema = mongoose.Schema({
type: { type: String, lowercase: true},
value: { type: Number},
timestamp: { type: Number},
device: { type: ObjectId, ref: "devices"}
});
module.exports = mongoose.model('datapoints', datapointSchema)

Answer 1

Manually updated the field in mongodb from charging-status to chargingstatus, as no useful answer was produced.
It's a workaround and should be considered unresolved.
Final code ended up looking as such:
var cursor = calcpoints.find({device: device._id}).where('type').equals('chargingstatus').sort({timestamp: 1}).cursor();
