I try to extract data from response but in Fiddler I see

And when I copy this content to [https://jsonpath.com/](https://jsonpath.com/) I see

I guess this is a cause why I get error like \> request\_11: Failed to build request: No attribute named ‘MyConnectionToken’ is defined 1 (50.00%)

Is it possible to handle this kind of reposne in Gatling? Or the only way is to use regex?

I test it on [https://regex101.com/](https://regex101.com/)

And I added .check(regex(“a-zA-Z0-9=/+{152}”).find.saveAs(“MyConnectionToken”)) but in result I still see \> regex(a-zA-Z0-9=/+{152}).find.exists, found nothing

Ok, yesterday I fixed issue with regex, correct should be [a-zA-Z0-9=/+]{152} but now I get error \> request\_9: Failed to build request: No attribute named ‘MyConnectionToken’ is defined. And now my question is, how can I define it? In other case I got token in header

 ![2019-10-16 07_15_19-Progress Telerik Fiddler Web Debugger.png](https://europe1.discourse-cdn.com/flex013/uploads/gatling2/original/1X/9e9d178a1088723a7c2ce40d5f1955856754071a.png)

And I guess in script it is defined here:

 ![2019-10-16 07_16_48-C__Gatling_user-files_simulations_logingood.scala - Notepad++.png](https://europe1.discourse-cdn.com/flex013/uploads/gatling2/original/1X/dea486f0e4d27d788f6b69416fcd85cb82b08343.png)

But token which I extracted is not in header but in body, here is the response header in Fiddler (on bottom)

And the body content

 ![2019-10-16 07_19_47-Desktop.png](https://europe1.discourse-cdn.com/flex013/uploads/gatling2/original/1X/72a8b9593afe040262611ed4e06a1329cae710bc.png)

How can I define it? Should I create structure similar to headers\_1 map? If yes what should be included? Thanks in advance.
