geofenceIds array is empty for GET devices API

I have added a device and linked some geofences to it using permissions api. Now, when I request /geofences?deviceId=id I get the device's all geofences that I linked. But when I request GET /devices api for same device, I get geofenceIds: [ ] i.e., empty array. Why is it so? Is there anything else to do?

Thank you. It helped.

@vikas please explain how did you fixed ?
In traccar backend we attached geofences with devices, but in API, it return blank,
Please write your guide / tips so it helpful

@SnippetBucket Technologies I'm not in touch with this stuff now. But I remember, this wasn't an issue. It's basic a functionality. I didn't know much about it at that time, so I asked it here.

So basically, geofenceIds: [ ] is a list of geofences in which your device currently is.

But /geofences?deviceId=id gives you list of all the geofences you've created.

So there's a difference. Suppose you've created 3 geofences A, B and C. But you're device is in A, you'll get something like geofenceIds: [A]

And if you use /geofences?deviceId=id, you'll get A, B and C.

Hope it helps.
