I tried to implement the NodeJS server input with json input data but i think there is a issue with the handling of this kind of data: request doesn’t end end is running into a timeout. The workflow is not catching the posted data and when i dug deeper i did find, that inside of the WF folder the request does something weird. When i post xml form data to the same address the data is not handled as attachment. but when i post json format the WF is handling it as an attachment and is creating an folder and inside of it the json file. when i post a regular attachment there is no such folder.
It would be nice of someone else can test this out.
to create json request you can use: https://reqbin.com
as i can only post 1 image (why??) here is a link to the images:
