Context

Debug logs

[christocracy]

are you watching the logs and using debug: true? There's a JSON error being printed to the logs for you to look at.

[christocracy]

timestamp is an ISO-8601 formatted String (eg: "2019-02-28T10:44:28.157Z").

You are telling the plugin to generate a json object like this:

{
  "timestamp": 2019-02-28T10:44:28.157Z
}

You are responsible for quoting the data

```json
{
  "timestamp": "2019-02-28T10:44:28.157Z"
}

It's like this:

{"locationTemplate":'{"timestamp":"<%= timestamp %>"}'

This is the JSON sent to my server now with all the variables. ,{} is appended to the end.

Template is
httpRootProperty: 'data',
locationTemplate: '[{"lat":<%= latitude %>,"lng":<%= longitude %>,"heading": <%= heading %>,"speed":<%= speed %>,"accuracy":<%= accuracy %>,"timestamp":"<%= timestamp %>","event":"<%= event %>","activity_type":"<%= activity.type %>","activity_confidence":<%= activity.confidence %>,"battery_level":<%= battery.level %>,"battery_charging":"<%= battery.is_charging %>" }]',

{"data":[{"battery_charging":"true","speed":-1,"battery_level":1,"accuracy":65,"event":"motionchange","activity_type":"unknown","activity_confidence":100,"lat":52.000290105969263,"timestamp":"2019-03-01T14:44:13.813Z","lng":-2.1282378635378132,"heading":-1},{}]}

Yes, [ ] templates are problematic. The plugin doesn't know where to append the extras object so it pushes it onto the Array. You'll have a much better time with { } templates and modifying your server to consume a different format.

else if ([location isKindOfClass:[NSArray class]]) {
            if (_type == TS_LOCATION_TYPE_GEOFENCE && _geofence[@"extras"]) {
                if (!_extras) {
                    _extras = [_geofence[@"extras"] mutableCopy];
                } else {
                    NSMutableDictionary *tmp = [_extras mutableCopy];
                    [tmp addEntriesFromDictionary:_geofence[@"extras"]];
                    _extras = [tmp copy];
                }
            }
            if (_extras) {
                DDLogWarn(@"Appending #extras to last index of [Array] in JSON template");
                [location addObject:_extras];  // <--------------- HERE IS YOUR EXTRA {}
            }
        }

You should be seeing this warned in the logs:

⚠️ Appending #extras to last index of [Array] in JSON template
