On v1.0.1 and 1.0.2 of the library you can receive this error in certain situations where the SQL being passed to the listener is missing.

Example of data being passed into the listener:

# Debug:{"sql":{},"bindings":[],"time":362.02,"connection":{},"connectionName":"mysql"}

The error that occurs:

   ErrorException

  explode() expects parameter 2 to be string, array given

As a quick fix, inside of ListenQueries I replaced

$sql = Str::replaceArray('?', $normalizedBindings, $query['sql']);

with

$sql = !empty($query['sql']) ? Str::replaceArray('?', $normalizedBindings, $query['sql']) : null;
