A failed reference occurred in a prior request.
Explanation
A reference for an expected data substitution is null.
System action
None.
User response
To find the failed reference, open the test and
go to the substitution site. Right-click the substitution site and
select . 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.
