Why do I get the error "Undefined function or variable 'processBarEvents'." when executing Bloomberg data retrieval for intraday tick data with "timeseries"?

I am using the Datafeed toolbox to perform Bloomberg Desktop data retrieval for intraday tick data using the "timeseries" function, however I find that when I run the following code to do this:
c = blp; temp = timeseries(c, 'SPY US Equity', {datestr(now-(2*365), 'mm/dd/yyyy HH:MM:SS'), ... datestr(now, 'mm/dd/yyyy HH:MM:SS')}, (5/(24*60))*60*24, 'Trade');
I get the following error:
Undefined function or variable 'processBarEvents'. Error in blp/timeseries (line 446) v = bBarTsObj.processBarEvents(blpUuid, blpIdentity, b.session);
Why could this error be occurring?

This issue occurs when using an outdated version of the "blpapi3.jar" file which ensures that Bloomberg commands work correctly.
To resolve this you can get the latest version of the JAR file using the
WAPI <GO>
command from the Bloomberg Terminal.
Please see the Installing Bloomberg and Configuring Connections documentation page for details on how to add the updated JAR file to the MATLAB Java Class Path.
