RegEx matching and null value

["Sklar, Emerson" <ES...@hpti.com>]

Hello fellow JMeter users!

I am trying to strip out a jsessionid value using the Regular Expression
Extractor. 

When using a regular expression which definitely should not match, the value
which is returned is the specified default value (as is expected)

However, when I have patterns and setting which should match, the variable
has value 'null'.

I've tried this both with a pattern to strip it from the URL and from the
headers, and get null each time.

Any advice?


Thanks for the help!

Hi,

please share the complete settings you use in your Regex Extractor.
Is the Extractor a child of the Sampler in question?
