> {{getSlaveDetails()}} prints out the properties it retrieves as JSON following "SHALIN:" -- see the log excerpt above. {{timesIndexReplicated}} is 2 instead of 1 because there was an unexpected replication failure: {{timesFailed}} is 1; if the assertion at line 666 were not there, then the one asserting zero replication failures, at line 668, would fail.
