Link to your project: N/A
Context

The postTemplate information is never sent to the url provided in the configuration of BackgroundGeolocation. Additionally, tasks are never ran when the app is terminated even though stopOnTerminate is set to false.

Expected Behavior

The postTemplate should be sent to the url provided in the configuration of BackgroundGeolocation.

Actual Behavior

There is no indication that the postTemplate information is being sent to the provided url on the app's side. The back end does not claim to have received any information from the app.

Possible Fix

Steps to Reproduce

Define a BackgroundGeolocation configuration as shown above.
Run the task based on location updates using BackgroundGeolocation.on('location')
Check for an indication that information was sent on both the front end and the back end.

Context

Trying to send location information to a back-end, where it is then sent into a database. While it is possible to send information through BackgroundGeolocation.on('location'), this does not allow for the sending of location information when the app is terminated.
