webhook error

[stefan]

Hello
I try to use iotope:node as webhook. But everytime when I apply a touchatag-Chip on the reader, it causes the following java-exception:

{"application":null,"fields":null,"targetContent":{"tagType":"LEGACY","blocks":[

Looks like the JSON-Object contains html or something else.
The webpage, that retrieves the HTTP POST, noticed that the POST-content is empty.

May anybody help?

Looks like activity is very low here. Has no one an idea about this?

I've been looking into this... but I'm not sure what it is... I think the problem is in the response you're server sends. The node expects nothing (not XML) or JSON

[Alex Van Boxel]

Yes I'm sorry for this. I'm afraid most of the time on my IOTOPE project is spend on Android (for events). The Java counterpart is still being worked on (I'll be preping it so it well work on a raspberry pi).
