My Operations team had shared a prxdat file with me, to make a few modifications.
On attempting to load the .prxdat file from project navigator, I am getting a null pointer exception.

Zebratester Console:

java.lang.NullPointerException
at dfischer.proxysniffer.ProxyDataRecord.readObject(ProxyDataRecord.java:786)
at dfischer.proxysniffer.ProxyDataDump.readObject(ProxyDataDump.java:537)
at dfischer.webadmininterface.PopupDirectoryNavigatorWeblet.execute(PopupDirectoryNavigatorWeblet.java:567)
at dfischer.femtowebserver.httpd.HttpdProcessEngine.execute(HttpdProcessEngine.java:259)
at dfischer.femtowebserver.httpd.HttpdThread.run(HttpdThread.java:134)

Note: The .prxdat file, along with the .csv input files, are in the ‘ZebraTester\MyTests’ folder.

  This issue is due to a version inconsistency.

  If you record a ZT script in a newer version, and try to replay it on an older version, you can get errors like this. The solution is to make sure that you are recording and replaying in the same version across your team, or at least across machines.

  The customer who originally put in this request upgraded their ZT versions as described in the above paragraph, and their issue was resolved.
