Description
[Regression] Mctimings crashes when trying to get timing data from couchbase. This is due to it not finding a "error" key, which is looking for so see if there was an error on the server side. However, if it does not find it then we should continue parsing the json data correctly.
Fix for this is to use the find method of nlohmann::json to see if the error key is present, if not we will carry on parsing the data as before.
Error message produced by mctimings:
