I've created in Jmeter the follwing:
HTTP Request (first one)
(Regular Expression Extractor) for the Response Body (I set the name of the variable, and put the correct regular expression,which works fine and returns the searched pattern)
(ForEach Controller) to iterate the Array (and of course I put the name of the array variable, and the ouput variable name (index))
another subsequent Http Request under (ForEach Controller Level) (then I put the value index of the array on the path like: /${smalpl_index}
Now I expect the second http Request below the (ForEach Controller) make a new Request based on the index Element of the Array from the Regular Expression, however I got null on the request...(see below)
Hier you find all the screenshot of the test scenario:
