RPXD0019E

A failed reference occurred in a prior request.

A reference for an expected data substitution is null.

None.

Fix

To find the failed reference, open the test and go to the substitution site. Right-click the substitution site and select Go

To > Reference. When troubleshooting failed references, start with the first error message. The first failed reference can cause subsequent failed references. Search the test log for unable to extract to find the first error message.

• Examine the request that generated the response. The request contains a value that might need to be correlated.

  For example, the request might contain a username that must be unique to play back the test successfully. In that case, use a datapool to provide a list of unique username values. You might need to manually correlate a value by using the Test Data Sources view. Values that typically are correlated include timestamps, dates, ids, and other alphanumeric strings.

• If you no longer need the data correlation mentioned in the message, remove that data correlation from the test.
