Debug Output

https://gist.github.com/yaleman/29da2505adbd00df97f695d96e9767f9

Expected Behavior

Logs to be processed successfully, I'm happy for the coercer to handle them...

Actual Behavior

Errors in the logs stating vector::internal_events::journald: Invalid record from journald, discarding. error=Error("invalid type: sequence, expected a string", line: 0, column: 0)

Example Data

Additional Context

Only NetworkManger events have a SYSLOG_FACILITY that's an array:

"SYSLOG_FACILITY": ["DHCP4", "DHCP6"],
