Not printing a msg onEnter

It complied successfully. However, it is not giving any notifications in logs.

It is not printing the massage below when the beacon is on my desk.

        let zone = ProximityZone(tag: "desks", range: ProximityRange.near)
        
        zone.onEnter = { ProximityZoneContext in
            print("Entered near range of tag 'desks'. Attachments payload: \(ProximityZoneContext.attachments)")
        
        }

What does the ‘get output frames failed’ message mean?

Only the first two lines of these logs are for the Proximity SDK, the rest is unrelated.
