Getting * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '* -[__NSPlaceholderDictionary initWithObjects:forKeys:count:]: attempt to insert nil object from objects[2]'

I am getting this error on my iOS phone whenever it scans an EID beacon frame.

XCode 11,
"@lg2/react-native-eddystone": "^0.1.5",
"react-native": "0.61.5",

got the same error here

I have also faced this issue. I believe its mostly related to iOS 13.

I am using "@lg2/react-native-eddystone": "^0.1.5"

-[Eddystone centralManager:didDiscoverPeripheral:advertisementData:RSSI:] Eddystone.m, line 124

Hi, im looking at this project currently, did anyone get a fix to this? thanks

I fixed the issue. The issue arrises when beacon.txPower (object[2]) or beacon.rssi (object[3]) is null.

To fix this, in Eddystone.m (within the pod) update line 127 and 128 from:
@"txPower": beacon.txPower, @"rssi": beacon.rssi;

to this:
[NSString stringWithFormat:@"%@", beacon.txPower], [NSString stringWithFormat:@"%@", beacon.rssi]

Alternatively

I added an if statement to catch nulls and this worked also

just wrap that whole send event with

if (beacon.txPower != NULL && beacon.rssi != NULL)
