Hi,
I'm struggling with adding two fields then put this value into another field.
I use this article https://blog.teknkl.com/extremely-strange-webhooks-exploring-http-range/ to walk step by step to find the solution. I created a web-hook, import all files from this file rangehook_mathjson_files.zip into marketo.
But when I run this web-hook in response I got whole file instead a just piece of it set by "Range" value in request headers.
Please see this screenshot: https://www.dropbox.com/s/6zzos7j4pu9aeov/Screenshot%202021-07-02%20at%2015.04.19.png?dl=0 , it should look like this:

"It sounds like the Range: header isn’t being sent correctly." -> exactly, I feel the same.
In my Postman this is working fine, in example above we adding 24 + 1 = 25, so it's ok.
But in Marketo response in wrong. Below I attach images step by step how I configured it:
with this settings I get in Marketo:
In 99% I'm sure that sth is wrong with {{lead.Behaviour Score}}
But I have no idea what to do or check next : (
