I have created an regular expression to extract CSRF token from the HTTP Headers and storing the value in the reference name CSRF_TOKEN by following this How to Load Test CSRF-Protected Web Sites

I using this variable in POST Parameters of another HttpRequest as below

csrfmiddlewaretoken=${CSRF_TOKEN}

Here ${CSRF_TOKEN} is not getting evaluated and the server is getting the middleware token as csrfmiddlewaretoken=%24%7BCSRF_TOKEN%7D

It got resolved. I identified that, if the regular expression is not matching any value and there is no default value specified, then JMeter is not treating as a dynamic variable. I corrected it by fixing regular expression. it starts working. Thank you.
