(mongodb >= 1.0.0)
Thrown when the driver encounters a runtime error (e.g. internal error from » libmongoc).
       Contains an array of error labels to go with an exception. For example,
       error labels can be used to detect whether a transaction can be retried
       safely if the TransientTransactionError label is
       present. The existence of a specific error label should be tested for
       with the
       MongoDB\Driver\Exception\RuntimeException::hasErrorLabel(),
       instead of interpreting this errorLabels property
       manually.
