Invalid dictionary key

I have a napalm-logs server injesting syslogs from a test vmx. I'm using the default publisher for the napalm-log server (zmq). Everything from the napalm-log server looks correct. It gets the log from vmx and the formats the syslog message. I'm running a zmq client and see the structured log:

{'yang_message': {'bgp': {'neighbors': {'neighbor': {'192.168.140.254': {'state': {'peer_as': '4230'}, 'afi_safis': {'afi_safi': {'inet4': {'state': {'prefixes': {'received': 141}}, 'ipv4_unicast': {'prefix_limit': {'state': {'max_prefixes': 140}}}}}}}}}}}, 'message_details': {'processId': '2902', 'severity': 4, 'facility': 3, 'hostPrefix': None, 'pri': '28', 'processName': 'rpd', 'host': 'vmx01', 'tag': 'BGP_PREFIX_THRESH_EXCEEDED', 'time': '14:03:12', 'date': 'Jun 30', 'message': '192.168.140.254 (External AS 4230): Configured maximum prefix-limit threshold(140) exceeded for inet4-unicast nlri: 141 (instance master)'}, 'facility': 3, 'ip': '192.168.1.183', 'error': 'BGP_PREFIX_THRESH_EXCEEDED', 'host': 'vmx01', 'yang_model': 'openconfig-bgp', 'timestamp': 1593525792, 'os': 'junos', 'severity': 4}

I've installed Stackstorm with the napalm-logs pack. It connects to the napalm-log server fine and receives the message but it runs into this error:

Any ideas what may be wrong?

This is all running on a single host with Centos7. Stackstorm is 3.4.1 on Python 3.6.8
